Resource update - UMA specs online

Looking at the traffic flows into this site over the past few months, it seems that a fair number of readers have wandered in looking for more details on the technology underlying Unlicensed Mobile Access (UMA), as in the BT Bluephone and related fixed/mobile convergence proposals. Well, since last week the specs are online here http://www.umatechnology.org/specifications/index.htm. As a non-engineer, parts of it are duanting/unintelligible, but the consumer/service provider scenarios are interesting, as is the prominence of Wi-Fi as the bearer technology, versus Bluetooth, as in the first iteration from BT.
