I have to say that uugallery uses two independent licensing servers, it works even when the main site is down and it doesn't depend on it. I have to say that the last LivePornBlog's problem was that I forgot to manually add his license and that's why it didn't worked for him. Now it was fixed and we are moving further. Nevertheless, I added an extra check for licensing service to make sure that it works great in some peak situations.
WP2.5 support has been also added. Thanks to everyone
