At the moment it will open a number of channels, but I don't think there will be much support for this Cam, in the future, as the team have brought out the newer T-Rex 4.6 model.
This model is supposed to include non public packages but there has been very little to recommend it so far, and it has not had even TPS, which the Diablo Cam has, and even emulations on receivers are opening more at the moment.
Depending on what equipment you already have it might be better to stick with what you have and await further developments.
If you need something immediately compare the price of the Cam against the cost of a Technomate 1000 range receiver, and other receivers, as these are currently opening more than the Cam.
