First, thanks for the kind words of encouragement. Glad you are enjoying our project. I hadn't heard of OpenGTS before. Looks interesting. It's amazing how much good open source software is out there isn't it.

I've added OpenGTS to our todo list but note that we prioritize how we use our limited resources to help the largest number of users and this is kind of a highly specialized application. It would be extremely helpful if people in the OpenGTS community partner up with us to sort our the integration details and put together a prototype appliance with TKLPatch.
