Consider altering the SCP protocol just a touch.  As SCP stands right now it 
has a major flaw in that a single packet can be around four gigabites in 
length (the session length field is 32 bits).  Since the whole idea of 
SCP is to use small packets (breaking up large data across several 
packets) to give the capability of multiple 'streams' over a single 
connection, AND because I don't know of a single normal computer that could 
gracefully handle a single four gigabyte packet (considering that the 
computer could do nothing with the packet until it was fully received) I 
would strongly suggest reducing the data length to perhaps 16 bits.  When 
computers can handle 4gb packets I'm sure they will be using a protocol 
other than SCP.
