Did you use Yahoo IM, AIM, or Skype?
Yes, yes, and yes. Works fine.
What about every other service/protocol that users use today, and might be invented tomorrow ? Do & will they all work with NAT ?
Anyone inventing a new service/protocol that doesn't work with NAT isn't planning on success.
Do many others work as well or act reliably through NAT ?
Yes.
Will it stop or hamper the innovation of new services on the internet ?
Hasn't so far.
The answer to these questions isn't a good one for users, so as the community that are best placed to defend service quality and innovation by preserving the end to end principal, it is our responsibility to defend it to the best of our ability.
Firewalls will always break the end-to-end principle, whether or not addresses are identical between the inside and outside or not.

Maybe. Most of them are perfectly happy. Matthew Kaufman
