how much of the service source code is accessible ?

One non-neglectible part of the IETF success is due to accessible 
implementations like 
LDAP: Umich's LDAPv2
DNS:  Bind
SMTP: Sendmail 
...

If you want success in LDAP confederation, you need to create a
community 
of interest around some implementation of the proposed protocols.
