Server to server link and groups

Is it possible to share groups of users between servers?

Example:

Jive Messenger is running on computer “admissrv1” server and computer “admis134” server.

A group of users called “TestGroup” is created on “admis134” server.

A user “Test1” logs onto “admissrv1” as “Test1@admissrv1.”

Can user “Test1” on “admissrv1” add the entire group of users “TestGroup” that is located on the linked server, “admis134?”

I can add individual users to contacts for user “Test1” that reside on the linked “admis134” server because, but I cannot add a group of users sitting on the linked server.
