Yes. I tried with db_mode=1 and it behaved very strangely so I changed it to db_mode=3 (DB only).
Also tried $(branch(socket)[N]) to read the socket data within my script, but it always returns <null>.
I am now thinking it will be necessary to have one location table per site, but perhaps you could consider adding options in future releases to allow the lookup function to only select contacts where the socket matches one that this server is listening on.

I suppose you are using usrloc with DB-only to share registrations between multiples sites, otherwise the socket filter will not make sense, right ?
