[Operators] in-band registration [forever]

Hi all,
[un]fortunately our server is supporting 'unprotected' IBR and we are 
not going to disable/'protect' it during next few months/years. For sure 
there are also accounts used during attacks registered on our server, 
but I think this is the same on all XMPP servers with any open 
registration and administrators have to just take care of them (somehow).

@Peter - I find it very useful and simple way to register and do not 
want to complicate lives of our potential users. Therefore we are not 
running captcha (as 'security' module) for IBR - from my (and our 
server's) present point of view it's meaningless and today's attackers 
can breach it easy.

@Kevin - that your comparison is not completely right. I do not think 
that we need to move away from IBR. I like that approach for 
registration and it make sense to install XMPP client and register on 
any XMPP server trough using just that one application.

The only we need is to find the way how to protect our servers from the 
attacks in the efficient and effective way. (there is nothing efficient 
and effective known at this time) The response to this could be 
"xep-0268" - already proposed by Peter Saint-Andre on February this year 
- and I hope that all of us will push on developers of our XMPP servers 
to implement it once it will be available.

This is a question of making XMPP mature and I do not think there is 
need to 'move away from IBR' or 'block all XMPP servers with unprotected 
IBR from federation'.
IBR is a (nicest?) feature of XMPP and cannot be punished for 
'not-the-best' security implementation of XMPP. :-)
