I think about this, but then think 'Why would I use a technology that 
can't put 28 T1s in 45 megabit of bandwidth?'

I get it for stuff like g.shdsl metro-e, but in building or on glass, 
might as well keep it TDM, and save the capex and tickets.

I'm sure technology may mature down the road but for now I just don't 
see the payoff that it has, unlike VoIP does, where you actually save 
bandwidth doing it as VoIP
