A computer data signal embodied in a propagation medium is provided. The signal enables a variable number of data transfers and includes an initial connection source code segment and a data transfer source code segment. The initial connection source code segment establishes a connection between at least two devices via predetermined listening ports, with at least one predetermined listening port residing within each device. The initial connection source code segment also dynamically assigns a first data port within a first device, and transmits the address of the first data port to a remaining device via the predetermined listening ports. The data transfer source code segment is for each of the variable number of data transfer operations. The data transfer source code segment dynamically assigns a corresponding second data port within the remaining device and transfers data between the connected devices via the data ports so that the data is substantially simultaneously transferred between a variable number of devices via the data ports. Each pair of first and second data ports is established in response to each listening port connection.

1. A receiving data transfer device that receives data and data transfer attributes electronically transferred from at least one remote device originating a data transfer, the receiving data transfer device comprising:a delivery receipt system that generates a delivery receipt comprising data transfer attributes verification after successfully verifying that the received data is the same as the data sent by the at least one remote device; a certifying system that communicates with an independent certifying processing device that certifies delivery receipts, the independent certifying processing device sending receipt certification to at least one of the devices involved in the data transfer after processing a delivery receipt, which certification comprises authentication of the data transfer using a postmark of a postal authority which postmark is a unique digital characterization of the delivery receipt, wherein at least one successful data transfer to the receiving data transfer device is certified by the independent certifying processing device.
