@ Preston Re: Bad Idea and hard to implement.
Clearly you haven't been faced with this issue.
Having a choice isn't a bad idea. Like I said, we did just that. We bypassed building in Internet connectivity to our building's monthly assessment and going for a big discount. One reason was that it limited our individual choices even withing the cable provider. The second was who would run on the premise equipment like routers and wi-fi access points. I could but if I moved or was unavailable... oops!
We were able to do it, although the second cable / ISP got burned.
We have a resident who's in real estate and kept coming to the condo board meetings griping about not doing a deal that built in our cable to our monthly assessment. As if new home owners really cared.
I do agree with choice, but unless you can get a large enough group to move or want it... its not worth the cost and effort. 20+ years ago, I had a switched 56KB link in my apartment and then ISDN. I could do that because I had copper to the unit. Today... cable modem is the cheapest and best buy. If I could do FIOS... for the price... maybe.
