[JDEV] Server-based History

I was thinking of doing a hack on my personal server to do this, and then
save them to an area I can search and browse via the web.  The searching would
all be done with PHP scripts.  I later wanted to expand it to be a real DB for
it all, so I could run queries more powerfully.  The only reason I personally
accpet this is because I have server control, not a scare factor there.  For
the primary distribution of Jabber, I don't know where we lean on this subject,
I guess it's really up to you all to decide.
