Can IAX work without needing to set up some IAX server?  How effective is it 
in getting around firewalls?

The main reason a Jabber-integrated answer is interesting is to keep things as 
simple as possible for the user.  It should be click and go.  We already have 
a simple answer for developers: launch netmeeting or a SIP softphone and give 
it the IP address.  But this is horrible for users because in most cases it 
won't even work due to firewalls.

Johnny Talker sounds like it has a lot in common with an external application.  
Have a look at iChat AV sometime to see how this type of integration turns 
out.  iChat has a built-in SIP implementation that negotiates a voice/video 
session between users.  Since it is built-in, the UI is clean.  However, 
since it operates independently from the IM part, it is unfortunately about 
as effective as an external application.  In other words, it never actually 
works.

What can you say about these things?
