Now would be the time to quickly develop a "bandwidth counting/limiting" software & throw it up in advertisements to anyone ending in comcast.net. Yes i realize there is software out there already capable of fulfilling this need (DUMETER for example) but your surfers don't know that.
A huge # of Americans use Comcast & they all recieved an email in the past 2 weeks about the new limits, so its fresh in their minds right now.
Instructions & tips:
Develop bandwidth counting/limiting software
here is a quick idea of what you'll need it to do
1) count a users bandwidth usage (daily, weekly, monthly)
2) offer the user a "daily" cap i.e. 8gigs per day (will keep them under 250gigs)
3) offer a weekly cap
4) offer a media filter (block all flash video, all mp3 downloads)
make all of these features your key selling point on the landing page
Filter traffic by hostname (comcast.net) to a nice professional landing page
Charge $59.95 a pop (non-recurring)
Make sure to mention they can lose their service for up to a year if they go over 250 gig's downloaded & just how easy it is to go over that limit
Enjoy the idea, I don't have the time for it right now!
