ILS servers are only used for ILS clients. :)  So pretty much just
NetMeeting,  but there may be others floating about.  GNOMEMeeting
supports ILS.

>can an ILS server contain any information that is not netmeeting related?

Yes & no.  A DSA can have multiple roots,  one can be the dit used by
the ILS service, another can be the "normal" LDAP dit.  ILS breaks the
LDAP standard in a couple of ways so you probably don't want to try and
mix them.

No,  you can't use an LDAP server as an ILS server without a shim
layer.  I have an extensive ILS section in my LDAP presentation

Yep.

Yep.

LDAP has no "refresh" concept.  You need to use a shim layer
(netmeeting.perl) to manage these 'extensions'.
