[dev] Horde_Rdo: Many-to-many-relations between objects of the same type?

[Ralf Lang]

Hi, 

I wonder how I do many-to-many between objects of the same type/table in 
horde_rdo. 

$alice->allowsCall($bob);
array($alice) = $bob->mayCall();

Maybe it's a bad example as permissions could be handled by Horde_Perms but 
the point is I fail finding a suitable setup of the relations array to 
identify the two distinct participants in the 'through' table.

I could cheat myself out by making CallPermission an entity of its own but I 
have no distinct data to tell about CallPermission other than who allows and 
who is allowed.

Any suggestions?
