I can list many reasons for this to be a good idea; the only reason I think anyone would think its a bad idea is if they really didn't fully understand the concept or implementation; I don't mean this is a bad way (no easy way to say this; I don't know or assume to know your knowledge about this matter; but I believe the less I know about something the stronger my conviction is; the human syndrome); but from an ISP's point of view it may mean you're not selling as many IP Addresses; I don't see this as a issue personally; we need to conserve IP addresses; IPV6 may give us more head room but its not here yet and isn't a real solution; why do I need more than one IP address to start with? Selling more certificates; not an issue; in fact I'm trying to make a point for the ISP but I'm not doing so well; maybe you can express your reasons more clearly than just bad idea... maybe me; but I still think this is the best idea I have heard of in a long time; it opens up doors to do things I can't do now; SSL for one; I can only get 14 IP addresses to my location (I still believe I need only 1 remember); and each go to a server; if I have 20 web sites on each server; then I can't offer SSL at all; unless your doing dedicated servers; small guys like me who can't afford the equipment to compete with the big guys can't compete at all; in fact I can't service my own web sites with SSL let alone my customers. So please enlighten us to why this is a bad idea with specifics if you can and then I and others will have something to consider; I know you have your reasons; please share them, we all are interested in your opinion.
Thanks
