ICA has value since it provides as easy way to obtain an xmpp 
certificate with the oid defined ... which is usually a pain.
But this is just based on top of startcom - and the trust for startcom 
should come from web of trust, not because xsf vouches for it.
So xmpp ica is as trust worthy as startcom ca is.
If tomorrow we support other ca's, or possibly move away from ica, the 
protocol spec would still remain unchanged, and tls's web of trust will 
take care of certificate verification (for people with ocsp enabled for 

Which is why I mentioned that we could have a wiki of a page which talks 
about how deployers/admins (not developers) can obtain xmpp certificates 
(we do not have client certs there do we ?) from xca and point a link 
from protocol to that page as 'helpful info'. This could then be 
referenced by developers, admin and deployers; while we could keep it up 
to date more easily.

Not yet the last time I checked.
