I certainly wouldn't put it past the Pakistanis to support him. They have a long tradition of siding with the mujahidin and those who believe such as UBL. It's also possible that he is in areas of Pakistan largely ruled by local tribes. I know that he has a large amount of support in the Peshawer area. I have read many articles/books that describe the locals as VERY friendly to his cause.
We have heard some recent rumors that he may be in the Kashmir region or in India. Heck, he really could be anywhere as far as I am concerned.
