A sending system, which includes one or more computer systems including a
sending computer system, sends, via a predetermined transport, data
indicative of an intent to send an object from the sending computer
system. A receiving system, which includes one or more computer systems
including a receiving computer system, receives the data indicative of an
intent to send the object. In some embodiments, the receiving system may
analyze the data indicative of an intent to send the object and select an
appropriate transfer mechanism to receive the object. The receiving
system sends data indicative of an intent to receive the object at the
receiving computer system. The sending system may receive the data
indicative of an intent to receive the object, may analyze the data, and
