Your farm looks incredible! We'll have to have an Ubercamp Ireland or something so I can make it over.

As for VAT, I've really just been trying to carve out time to review thread's like this one where Al is providing significant feedback and examples. Lyle also posted an issue on d.o where we can start to think about patches and get a solution going... We may have another beta without this functionality, but as far as I'm concerned, I'd like there to at least be an API that other modules can hook into by the time we have a release candidate.
