A VDV area sounds like a good idea, as we are getting more questions on these topics now. "Tricks of the trade" also sounds like a reasonable candidate, as it would allow some neat semi-reference threads to be kept all together in one place.
The only thing I would add is that I don't think we should get carried away with adding extra areas unless they cover a clearly defined topic (or sub-topic), such as above.
Those forums which have four dozen areas on the index page might look impressive at first, but it soon becomes clear that there is a lot of overlap between areas and a lot of confusion as to which is the "correct" area for a subject.
