Hi Shane,
Welcome to the forum. I am pleased to see more interest in from a MediaPortal user.
I will maintain support for the existing MP features in VC, and in any case I think it's very unlikely that anything will change in MediaPortal 1 drastically enough to introduce any real problems for us. I can't make any promises at the moment for MediaPortal 2. I don't know anything about MediaPortal 2 but I suspect it is a radical change from MediaPortal 1. The first thing that would have to be done is the MpWifi plugin would need to be updated, and although it is open source, it will make more sense to let the original developers adapt it to mp2 if they are willing.
In any case, although the alpha of MediaPortal 2 seems to be out it will probably be a long time before it is really a good idea to switch over.
If you are aware of any areas that I need to fix or improve please let me know. I am happy to get feedback. I am aware of the current limitations interfacing with TV-Series, but I"m not sure what to do about that without support from the developers of that plugin.
In the new year I will try to take another look at MediaPortal, maybe clean some things up and post some information on the MP forums. Feel free to blow our horn for us though, since the more people you can bring over the more MP improvements you can expect to get.
