Hi Jim,
I'm not saying I'm against your below list - haven't thought about it enough yet - but an "ISP association" seems to imply ISPs - Internet Service Providers. Your list might be tending to an "Internet association" (it depends on what "so on" means I guess). It would be good to have an "ISP association" to stand up for ISPs.
An ISP to me means being obligated to register at BAKOM as a telecommunications provider ("Registrierung als gemeldete Fernmeldedienstanbieterin") *because* one is offering some sort of public Internet services. Such an obligation certainly covers a few points on your list. My 2cents worth...
Indeed "and so on.." is open. My point was more to say its not restricted (as Per Jessen said) to _ACCESS_ providers. You say it should (maybe) be limited to BAKOM registered providers, don't forget that the new BÜPF law draft includes non-BAKOM registered _SERVICE_ providers (like mail hosting) and I think such an assoc. should also protect them.
Participate is the preparation process and you'll have your word to say. If you wish to be founding member, you will also be able to amend the Statutes and get a vote during the foundation assembly.
See you! Pascal
