It singled out a lot of big services here:

- cisco.com and all webex jabber hosted services
- google talk and all google apps xmpp hosted domains (and it's more 
then you think...)
- All servers which run Openfire even if they support TLS, they seem to 
trample on authentication steps when they open a stream to a server 
which presents both SASL and DB
- All servers which (seemingly) are pre-1.0 (even those who don't 
properly tag their strean headers)

And beside this had some not so nice encounters with very buggy jabberd2 
servers which started to loop attempting to re-establish a connection 
(very fast beside) when the server closed down their streams.
