SETACL and virtdomains

[Andrzej Kwiatkowski]

Hi.

I'm using medium scale installation, with a lot clients domains, and 
mailboxex in mutliple domains.

Now we want to add to clients functions of sharing mailboxes with some 
apps from Kolab.

In docs i have found:

       * Domains are mutually exclusive - Users only have access to
         mailboxes within their own domain (intra-domain). The following
         example will not work: setacl user.jill at herdomain.com
         rick at hisdomain.com read.

Is there any workaround ? Patch maybe ?

TO share folder from user1 at domain.com to user2 at domain2.com in the same 
server ?
