It seems that we have two target audiences here.

1) Those that are working with XML-streams, and want to leverage them in an 
HTTP Polling scenario.

2) Those that are working with HTTP & XML, and wish to utilize non-persistant

Each audience wants essentially the same thing, and that's XMPP over HTTP.  
The only real difference in functionality desired between the two groups is 
the way security is conducted.  The first group would naturally prefer to use 
existing xmpp-core security.  The second group would be content with HTTPS.

I think that if JEP-25 is going to be replaced, we need to establish why it 
should be replaced.  Judging by the discussion so far, it seems that the 
rationale for JEP-124 is to provide an easier way for the second group to 
implement XMPP over HTTP, not that there is any particular deficiency in 
JEP-25.  This is not a good enough reason to replace the JEP, in my opinion, 
especially if all it would do is reverse the situation (second group happy, 
first group not happy).

As an aside, it is interesting to note that JEP-25 is useful for applications 
beyond XMPP, as it simply provides a generic bytestream over HTTP.  
Considering this kind of technology is already pursued outside of the JSF 
(just google for 'http tunnel' to see other products), perhaps the JSF is not 
the appropriate place to maintain such a spec.

Right, JEP-25 code has to be written, but it can simply act as a proxy to the 
Jabber server.  I believe this is how most available JEP-25 server stuff 
works.  jabberd is never modified.  The proxy doesn't even have to run on the 
same host, which is nice if you want JEP-25 access to a server that is not 
providing it.
