There are working corss platform solutions. 
> Skype works today, but we have several up and coming replacements.

Actualy, your only biggish problems with linux sip clients are coming
from varios firwalled/NATed network setups. STUN doesn't work in all

On linux I've been using KPhone, Ekiga(gnomemeeting), sip communicator
(a java client) and some homebrew for a while without major problems.
I mean using audio/video conferencing including group conferences.

Asterisk and SER are doing a fine job indeed. OpenMCU & friends are a
working platform. 

The real problems are not really technological. They are UI on the
client side and lack of sufficient sysadmin skills for deploying
decent VOIP setups.

The third problem is that more often than not, users on most platforms
will need holding their hands a bit until they get the best from their
hardware - microphone setups, echo cancellation, etc...

I can discuss the same in Cardiff, so we can possibly have a box here as well.

For practical conferencing meetings a good place to research is VRVS, 
as in vrvs.org - this is  Internet2 and High Energy Physicsonline
community, which is open to the public. I think it could be possible
to have a drupal section there. It is a web portal to H.323, SIP/SDP and
VNC. It supports virually any sip or h.323 setup including it used to
have sip communicator launchable from their website.
