Bluetooth PAN already exists which makes the whole name confusing. Sure it's not for peripheral connection, it's for actual networking (IPv4 comms). These two want to sell a PAN that isn't a PAN?? IF anything it should be Wireless USB, and certainly should be UWB-based.Wireless USB would leverage the existing massive support for USB, probably just with a different PHY (with OS extensions to provide for pairing). 
Bluetooth has been a dog (especially Toshiba) but it's now actually usable.
It's unclear what actual protocols will be used for this new 'standard' but it looks like 802.11 - this can't be good.

Two empty tin cans and a length of string are a serious threat to Bluetooth.

8 is one more than a piconet?
Cliffside, I hope, will be a darn sight more than BlueFule. Here's why: The stupid mobil phone OSs, won't let you do practical jobbys like a load of file transfers. You have to find a 3rd party to manage your mess for you. I hate BREW. I shelled out big for a RIM BB International 8830, prior to Iphone. The bloody BlueShite is useless! Dropped it with the USB/charger adapter plugged (it broke), and then there's NO way to transfer the voluminous Address Book. The BlueFly will only dart your snaps and jigs! I hope EVERY gadget that floggs Cliffside, will have ALL the usage profiles, you'd expect, without calling a plumber! This crap doesn't fly at MI-5, does it? Piss on BlueTeeth, or on the RIM.
