I've been following this whole thing pretty closely, seeing as how it affects my application (PokerAce Hud, an alternative to PV/GT+).
It appears Party doesn't have a problem with them. I've received one complaint from a user who got a warning email, but this user was also using PokerProphecy, which Party doesn't like.
Stars also doesn't like applications like PokerEdge, but has no problem (currently) with Hud applications.
By the way, I can't post here without plugging my app. You can download it here:
