You might want to investigate dropbear for the server side.  It's a
server-only SSH2 implementation.


* A small memory footprint - Dropbear can compile to a 110kB statically
linked binary with uClibc (and only minimal options selected).

Are you sure you have enough CPU for this?  People have issues with speed
on eg, older SPARCs, and they're faster and 32 bit...

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
