I cannot begin to compliment you enough. NetFlix surely must know that if someone like me is willing to sign up for their service after years of not believing in it just because it is in media center, that your software is worth their paying you to develop it.
In any case, I like a few others in the thread, would LOVE LOVE LOVE extender support. I am willing to donate toward development (so you can get an extender or whatever you need). I use my primary PC in a smaller room in my home but have 5 extenders throughout the house that I would love to watch the content on. I know that I won't be able to watch 5 simultaneous streams, but just one at a time would be so wonderful.
I have abandonded some of the other plugins that you described in your first post for the same reasons that you've continued development, but I have to say that whoever can prouduce an extender working plugin (even if not as great as yours is now) will ultimately have my vote.
Please let me and the other interested readers know how we can help you develop the application in this way.
