We are using 1.0.2f, no-ssl2 and no-comp do not appear to be defaults in that version.  Should heartbeats be turned off, or have recent version of OpenSSL taken care of any potential weaknesses there?

We provide config settings to disable ssl3, idea, and seed, though I think it'd probably be safe to drop idea and seed altogether.  I believe heimdal uses rc2, which precludes disabling that one.
