Perhaps we should use the install.xml feature to set things up differently for toolkit developers and site developers, then, to meet Lars's objection?
Joel's proposal is a long-term one (we won't have HTML tests until we integrate tclwebtest, for instance) but the sooner we start the better. Collaboraid's been writing automated tests for some of the work they've done in the past few months.
This task item needs a champion, and I think the TIP process assumes that the poster is by default the champion for any TIP opened up. That puts Joel on the hot-seat to coordinate our getting started on this task ... right, Joel? :)
