RE: SUA: Relay: SG-SG

Howard,

my two cents:
IPSPs by definition do not have relay functionality. They communicate
directly without involvement of any intermediaries and they don't have relay
capabilities. My understanding about SUA-relay is that it is a concept
similar to SG-SG communication for SUA I don't know where the details of
this are explained-.

Just wanted to tell that there are different opinions about the issues
discussed in this thread.

   Thanks,
   Tolga
