I have ~400 sites to start so we have the passwords follow a schema that
is programmed into a startup program to start everything and then depend
on filesystem security to protect that program.

I use the nCipher boxes extensivly, they run from $4000-10,000 depending
on modle (the $10,000 version can do 300 sigs/sec while the $4000 does 75)
They are wonderful for taking the load off of the CPU so that it can
instead be bogged down running CGI's :-)
