i think that, for TCP, you need a socket on the sending computer, too. 
for ack/nack, flow control, etc.

yes, it should allow you to open the outgoing socket. perhaps you would 
get into trouble if the previous remote computer is still sending things 
back to your local/sending computer. but the sequence number should 
protect you from that... i think it will be ok.

    solely in a computer program then the subject matter is not
    patentable in whatever manner it may be presented in the claims."
