We claim: 1. A vehicle communication network, comprising: a plurality of network elements disposed within a vehicle; a plurality of point-to-point communication links joining the network elements in a point-to-point configuration, the plurality of point-to-point communication links being arranged to communicate data packets between the network elements, and at least a portion of the plurality of point-to-point communication links being specified in accordance with at least two different shared-access bus protocols; wherein the plurality of network elements include at least one network element linked to two or mow other network elements through corresponding point-to-point communication links that are each distinct from each other, two or more of the corresponding point-to-point communication links being specified in accordance with the at least two different shared-access bus protocols; and wherein the at least one network element operates (i) to receive a data packet and (ii) to route the data packet over a given one of the corresponding point-to-point communication links. 2. The vehicle communication network of claim 1, wherein the at least one network element further operates to modify the data packet prior to routing the data packet over the given one of the corresponding point-to-point communication links. 3. The vehicle communication network of claim 2, wherein the data packet is specified in accordance with a first shared-access bus protocol and the given one of the corresponding point-to-point communication links is specified in accordance with a second shared-access bus protocol that is different from the first shared-access bus protocol, and wherein the at least one network element modifies the data packet for transport via the second shared-access bus protocol. 4. The vehicle communication network of claim 2, wherein the at least one network element modifies the data packet to include quality of service information. 5. The vehicle communication network of claim 2, wherein the at least one network element modifies the data packet to include route information. 6. The vehicle communication network of claim 2, wherein the data packet contains an arbitration field, and wherein the at least one network element modifies the arbitration field. 7. The vehicle communication network of claim 1, wherein the corresponding point-to-point communication links include at least one point-to-point communication link specified in accordance with a protocol that is not a shared-access bus protocol. 8. The vehicle communication network of claim 1, wherein the plurality of point-to-point communication links and network elements are configured as a switch fabric. 9. A method of providing communications within a vehicle, comprising: providing within a vehicle a plurality of network elements; communicatively joining the network elements in a point-to-point configuration using a plurality of point-to-point communication links, the plurality of point-to-point communication links being arranged to communicate data packets between the network elements, and at least a portion of the plurality of point-to-point communication links being specified in accordance wit at least two different shared-access bus protocols; arranging the plurality of network elements to provide at least one network element that is linked to two or more other network elements through corresponding point-to-point communication links that are each distinct from each other, two or more of the corresponding point-to-point communication links being specified in accordance with the at least two different shared-access bus protocols; and configuring the at least one network element to operate such as (i) to receive a data packet and (ii) to route the data packet over a given one of the corresponding point-to-point communication links.
