The system of claim 1 wherein each client is implemented in a set top box operable to provide interactive television services on the associated display. 3. The system of claim 2 wherein the network comprises one or more of an IP-based transmission infrastructure, a coaxial cable transmission infrastructure, a satellite communication infrastructure, or a telecommunications infrastructure. 4. The system of claim 1 wherein each client is further operable to capture user input data representing interaction of a user with the representation of the allocated virtual computer, and to transmit the user input data to a first one of the servers managing the allocated virtual computer, the first server being operable to provide the user input data to the one or more applications associated with the allocated virtual computer. 5. The system of claim 4 wherein the user input data are generated by one or more of a keyboard, a mouse, a remote control, a game controller, a joystick, a camera, or a microphone. 6. The system of claim 4 wherein the representation of the allocated virtual computer rendered by each client includes a cursor representation, each client being operable to render the cursor representation locally. 7. The system of claim 6 wherein the first server is further operable to identify a visual appearance for the cursor representation relative to the one or more applications in conjunction with providing the user input data to the one or more applications associated with the allocated virtual computer, and to communicate the visual appearance to a first one of the clients corresponding to the allocated virtual computer, the first client being operable to render the cursor representation to have the visual appearance. 8. The system of claim 1 wherein each client is integrated with the associated display. 9. The system of claim 1, wherein the one or more servers are further operable to: instantiate a pool of available virtual computers; andselect an unused virtual computer from the pool for allocation to the particular client in response to receiving the request from the particular client. 10. A computer-implemented method for providing virtual computing services, the method comprising: instantiating a plurality of virtual computers of different types, each virtual computer comprising a graphic display component and an audio output component;associating a set of one or more applications with each of the virtual computers, wherein the set of one or more applications that is associated with virtual computers of different types are different from one another in order to service different types of users operating the virtual computers;receive from a requesting client a request for allocation of a virtual computer according to a preference of a user operating the requesting client;allocating a particular virtual computer of a particular type to the requesting client in response to the request, the particular type of the particular virtual computer being directed to the preference;generating graphic display data for the set of one or more associated applications by the graphic display component of the particular virtual computer, and generating audio output data for the set of one or more applications by the audio output component of the particular virtual computer;encoding the graphic display data and the audio output data from the particular virtual computer for transmission over a network to the requesting client such that the encoded graphic display data and the encoded audio output data are synchronized;employing a codec that is operable to employ a plurality of time stamps associated with the graphic display data and the audio output data while encoding the graphic display data and the audio output data;deriving the time stamps associated with the graphic display data and the audio output data from a simulated reference clock;driving the simulated reference clock according to a data rate of the audio stream by computing relative time stamps of successive audio captures of a fixed amount of audio data captured; andtime stamping each video capture with a last audio time stamp used. 11. The method of claim 10 wherein the network comprises one or more of an IP-based transmission infrastructure, a coaxial cable transmission infrastructure, a satellite communication infrastructure, or a telecommunications infrastructure. 12. The method of claim 10 further comprising: receiving user input data representing interaction of a user with a representation of the particular virtual computer; andproviding the user input data to the one or more applications associated with the particular virtual computer. 13. The method of claim 12 further comprising: identifying a visual appearance for a cursor representation relative to the one or more applications in conjunction with providing the user input data to the one or more applications associated with the particular virtual computer; andcommunicating the visual appearance to the requesting client for local rendering of the cursor representation by the requesting client. 14.
