Well, I do know of someone who is working on a cryptolib package that will
attempt to include a ton of crypto methods into a single library that
anyone can link to.  From email exchanged with this person it seems that he
is looking to get a unix version up and then let people port it around.
The math lib stuff is the most recent sticking point he was having: there
arenot many fast multi-precision math packages out there that are free (and
gmp does not cut it, he wants to be able to let anyone use the code however
they want...)  So far he has checked fgmp and bignum, but if anyone knows
of a fast package that has a berkelyish copyright let me know and I will
pass it on...

Maybe I can set up a list for this if people are interested.  The existence
of such a beast, even in a rudimentary form, would be useful to quite a few
people I would bet.  I will push him a bit to see if he will dump what he
has now into a package so that others can help out.
