I did actually make an attempt at that once for BGGP5 [0]. (That is, making a minimal, horribly insecure 'client' implementing just enough behavior to get a response from a server.) But I got demoralized by how much space the binary blobs for the crypto algorithms took up, in comparison to the actual machine code.

You could borrow the output of the perl scripts from openssl.

I'd really like to see a TCP/IP stack written in native forth (if anyone needs a really good therapist, that sounds like a _great_ project to try ;)

I mean, it doesn't look _that_ daunting, but the fact that noone seems to ever have release an open source version (there are rumours of proprietary stacks though) speaks for itself.
