I thought extending IDLs does not raise compatibility issues?
i.e.
old.idl:
module X
{
   interface IX
   {
     void foo();
   };
}

new.idl:
module X
{
   interface IX
   {
     void foo();
     string getLocation()
   };
}

"clients" using old.idl can communicate with "servers" using new.idl 
without problems
