One of the things I've said we need to work on is deployment. There's work going on to make build up easier than strip down - but in the meantime, the RuntimePackager is getting some long needed improvements. The current version asks you to check the classes you want to keep by namespace or category - most people (myself included!) would rather do that by Package.
So, that's what I've been doing this afternoon - testing the latest RTP build by trying to produce a BottomFeeder runtime in the 7.4 development stream. It's been worth doing - a number of small flaws have been identified, and I think it looks like RTP should be a better tool when VW 7.4 ships.
