For those of you who found issue with Pro Tools 9 NOT having TDM support here's a bit of news.

Universal Audio Becomes RTAS Plug-In Developer For Avid Pro Tools

I can only speculate that this means, HEAT may become available as a powered Plugin for the UAD-2 Cards. Of course, this now means you will have to buy another piece of hardware for the extra functionality. $700 is a far cry from $8000 for an HD1 card.
