Have to balance emergency services availability (E911) with low power... if you coupled a lightweight signaling to the switch that the phones was the only port there then you could easily run at 10Mb or something that reduced the number of pars and kept the power draw low as well.

Keep policy configuration very simple (yes, via a GUI :-)).

I remember having commented on a similar subject, just a few weeks ago, after ten years of not touching the subject. I liked your comments, and couldn't keep wondering what happened to the "active networks" http://www.sds.lcs.mit.edu/activeware/ from the standpoint of "push" configuration of all sorts across entire infrastructures (thinking now of VMotion-ing layer 2 and 3 virtual devices). I recall having tried some research, on my own, in 1999, focused on ANTS, and things appeared so exciting at the time - i.e. 'Nirvana" for network operators (while nightmare for security people, of course) ...
