[ppml] Revision to 2008-3

I disagree that a third designation is necessary at all. What happens if 
for any reason a non-profit 'community' network operator folds, and a 
commercially driven ISP buys up their assets?

My opinion is that any entity providing any form of Internet service 
should be classified as an Internet Service Provider.

Whether the user of the service is classified as a 'member' or a 
'customer', both designations could be put under an umbrella called 
'subscriber'.
