That's the problem, normal people can't set up that lacking that
fixed address. Yes, of course, there is dyndns and such, but...

Carlos, you're loosing me - what does a normal person need a STUN
server for? Unless that normal person wants to provide VoIP
services, he or
she has no need. A STUN server has one single reason for being - to
enable clients on a NAT'ed network to be reached from the outside.

Two meanings. One, that a normal client has to use a STUN server that
somebody else creates,

Right. It's one of the options.

and that a person that tries to setup asterisk
will probably also have to setup a STUN.

Depends on what that person wants to do. If he wants to establish calls
_to_ SIP-clients behind NAT routers, something is required to keep the
client-side NAT table up-to-date. STUN, keep-alive, Andrei mentioned
SIP NAT traversal (I have no experience with the latter).
