I’m sure there’s some things that don’t work properly. If you’re doing anything big with this you probably want to write some ‘destructive’ update functions for adding, etc. At [...]

A [...]
I really (really) want to participate in the Wellington “Summer of Code 2.0” (blog), but it is Wellington-only… and I doubt any of the companies involved want to take on an unproven second-year student to work remotely on their software. Argh!
