Ask HN: How are you dealing with VATMOSS?

I'm looking to start an open discussion on HN related to VATMOSS and how US-based tech companies have been dealing with it since its release on Jan. 1 of this year.

Did you roll your own solution? Use a 3rd party provider? Find some obscure loophole to get out of it?

Did your implementation to collect VATMOSS impact your PCI compliance?

Really, I'm just looking for any stories, solutions, or problems related to how your company incorporated VAT collection.

Thanks!
