Yeah, only my second post and already I'm asking for something... :lol:
While using MySQL and Postgres are very cool for heavyweight applications, a binding to Sqlite would be advantageous for more portable, data-driven standalone apps. I've used both MySQL and Postgre to power the backends of some websites and while they work exceedingly well, they aren't light enough for less data intensive apps. BerkelyDB is TOO light in many cases.
