I'd like to see SQLite as one of the options as well, for
less-intensive stand-alone setups and for PDA's, etc.

Having rewritten the in-memory code a few times to make it faster
with large amounts of data, I can appreciate having a separate
database to hold this info.  It also gets us a long way towards both
the persistence goals and the distributed app goals.

The in-memory database strategy has been stretched a bit too far as
it is.  It's a quad-linked list, with a separate hash table to speed
up searching.  A convoluted mess.

I looked at WxWidgets a while back, when Qt wasn't free for Windows
and so wasn't an option for us.  There were some things about
WxWidgets that turned me off back then, but I'd have to see if I
wrote down notes as to the reasons.  I may not have.

Now that Qt is free for use with GPL'ed applications it is by far
the more attractive option.

There's no reason that the back-end couldn't be written w/o GUI
code, then GUI applications written with different widget sets to
talk to it.  People that didn't like one widget set could replace it
with another.  If we're careful in the design this replacement could
be made easier to do.
