Another note on this:  doesn't this destroy your "plausible
deniability"?  If there is some DSA key stored on my computer, that I
keep showing to everyone I chat with, and is recoverable if my computer
is seized...what is deniable about that?  

Until someone can explain that to me, I prefer to generate new keys for
each communication session.
