"v3.3" referred to the software version of the UMich LDAP kit, not the
protocol;  the protocol supported is more LDAPv2 (or LDAPv2+ as some say).

AFAIK, a number of now commercial LDAP products also began with the UMich v3.3
kit and then developed off in their own directions (ie., separate code trees).

Sure.  Netscape/iPlanet Directory is an LDAPv3 server, as is the LDAP
front-end to NetWare 5.  Active Directory is supposed to talk LDAPv3 too.

For varying values of "fully", most probably.  :-)  As has already been noted,
there's no requirement that LDAPv2 clients be supported (though they probably
will be supported to a reasonably large extent).

No - OpenLDAP 1.x doesn't *require* the ISODE libraries either, they're only
used (if memory serves) for the LDAP/X.500 gateway which has since been
deprecated in the OpenLDAP kit due to lack of support/interest/development.

As above - the LDAP/X.500 gateway has been all but dropped from OpenLDAP;  
ISODE libraries aren't required for standalone OpenLDAP use.
