I know this varies greatly based on location but it would be good if you could include a section on legal challenges given that there are many municipalities actively trying to discourage any sort of competition.
Secondly, looking at common.net, how did you arrive at 75Mbps as the offering speed?
I actually have in my plan to include a section like that, not quite there yet though. But in general legal challenges are less of a problem than you might think - most of the legal challenges you hear about with running an ISP come from things like who owns/is allowed to use conduit, right of way for trenching new lines, those kinds of things. With wireless you sidestep all of that.
75mbps is what we feel like we can reasonably achieve across our entire user base. Most of our customers are up to double that.
Also I should add - what I've found is that the municipalities are somewhere between neutral and really excited to have another provider in town, as long as you're not putting too much ugly equipment on people's houses. Sometimes the municipality is a really great partner and will help find relay sites, etc. It's the incumbent cable cos who don't like the competition.
