Subject Re: [Mitosis] ADS cluster management

I've thought about using these kinds of generalized frameworks to help piece
together various aspects of the LDAP replication system. At various stages I
thought that these toolkits may be as you thought heavy.  In most cases, I
felt that they were hard to fashion into something LDAP specific.  I've
always felt like you have to create the message transport layer and directly
implement the group management since it was defined by the replication

Also I think there's something like this out there used by JINI: Javaspaces
I think.  FYI JINI is now an Apache project called River I think so the code
should be there.
