One quick note I'd like to add:

Looking at the website, it seems to be pretty game-generic, however with the GCP add-on for WOW, and the examples given for WOW, it lends me to believe that its only really been tested thoroughly for use with WOW.

I multi-box LOTRO, I used to multi-box DAOC... there are smaller communities of multi-boxers for these non-WOW games and more (EQ1, EQ2, etc.). They don't tend to allow the same kind of add-on/mod support that WOW does, so before getting involved in any product, it's nice to know what will be and won't be available features, and whether it even works with the product. A listing on your website, or a 7-day trial would be a very nice thing to have for people to make sure that it works on THEIR hardware configuration with THEIR prefered MMO.
