I have a 1Mbit/s broadband connection sitting idle for most of the

using the Watt-32 tcp/ip stack.

I "only" need to get my hands on the source-code. Who could
help me with that? A non-disclosure agreement is okay" as long
as the binary is free.

VectorLinux should run fine on a 486 if you have 16MB of RAM (maybe less 
without the gui), run the command line S@H client.  You don't need the gui 
so the HD space should be well under 350 MB.  http://www.vectorlinux.com/

System Requirements:
VL is designed to run well even on older hardware. To run VL,
you'll need at least a 386 processor and 16MB RAM. A full install
of VL requires 350MB hard drive space.
