ProControl talks a big game with their ProLink.Z

I've had no chance to play with the software yet, but curious what 3rd party systems it is compatible with? Does it play well with Lutron lighting (or others), HVAC (If so, which ones?), and security?

Seems like a really cheap entry, any pitfalls? Seems like it'd be an easy sell to those folks looking for cheap now, but who might like to upgrade later.

I'm always torn on those jobs. I know I could easily get the job if I spec a MX-900 and a RF-260, but when they want ipad control, or add HVAC integration, we're almost starting over.
