I can give you an insight about the design ideas
of groups in the Kolab groupware solution.

Not initially. The group account is similiar to a regular account,
except that the "calendar" system user can write into the default
calendar initially.

You then can use ACLs and the freebusy incidences-for setting
to define which users are part of the group and how they can use it.
This is done by logging into the group account.

This is more or less the idea.

Note that there are also two other types of "groups" in Kolab
in addition to group accounts: (a) personal distribution lists,
(b) global distribution lists.

(b) can be set up with the Kolab webadmin or any other ldap speaking
(a) will be maintained on the client and saved as special form of contact.

I cannot say what the current state of implementation of Horde
towards (a) is.
