	Remember 8k would be very large for a file manager and I doubt that it would 
be that small. I've been thinking about a port of uIP for NitrOS-9 (with some 
additions to make the interface cleaner). The thought of a file manager is neat 
however, and I'll consider that as well. (I've had some experience with TCP/IP 
(wrote a stack for OS-9/68000) and file managers (wrote an ISO9660 file manager 
for NitrOS-9 and OS-9/68000).

	That'll give me some hardware to talk to!
