[WG-UMA] Article: Why the PAT?

I've written an article called "UMA: Why the PAT? <https://docs.google.com/a/forgerock.com/document/d/1UFFc3MJg5fPHfT5_oruAqxazYdvp6bMW30kCrpfurFM/edit?usp=sharing>" and I would be grateful for any review comments -- and ideas for publication options -- people have. This question comes up a lot, and the writeup has already been helpful. *Eve Maler*Cell +1 425.345.6756 | Skype: xmlgrrl | Twitter: @xmlgrrl
