I'm about to get my feet wet in this stuff...and was wondering if anyone had any experience with it?

Any tips, thoughts or advice?

...I'm already pretty comfortable with surround mixing and have most of the gear I need to pull this off. One of my media clients had inquired about it. I've been researching the hell out of it for the last few days and feeling pretty good about diving in and taking a shot at it. The cost is pretty minimal if you already have PT HD and a 7.1 monitoring rig in place. 

Would love to hear from anyone who has experience in this space.
