Well..  detection of the FON heartbeat is one way that an ISP could passively 
detect what you're running (ports 1812, 1813, 1937).  Just like running web 
servers on port 80 (or sort of).  More info here:

Well.. literally.. yes, it could be.  If "their business model" consists of a 
profit margin based on overselling their user to bandwidth ratio at 10:1, 
then with a bunch of FON clients they find that their BW costs are doubled 
due to only being able to offer a 5:1 ratio without buying more bandwidth... 
then you can see how they would be upset with such clients (not even talking 
about new client profit losses due to "peer sharing".
NOTE: I'm just playing the overly-greedy-capitalist-pig advocate here ;).

All that being said.. This really isn't a "problem" with the number of FON 
folks we see in SA, or even in Austin.  You literally have tens of thousands 
of regular, road runner customers for every one that might have a FON device.  
It's probably not worth their time.  Although still.. would not be difficult 
to set up to detect such clients.

All they have to do is "disallow" port 1937 use and a few others to stop fon 
users, not asking what's inside your network (just as some stop ports 25 and 
80 incoming):
	1812 udp - RADIUS auth
	1813 udp - RADIUS acct
	1937 tcp - ssh (heartbeat script)

Last I checked, without a special business account, they still block you from 
serving port 80 and port 25 traffic no?  I recently helped a friend set up 
custom apache and postfix configs so that they could serve web and email 
services from home... at least I thought that he was using road runner.
