Actually, no.  The issue is not extended-remote vs remote.  We have boxes
with multiple boards each running a kernel.  The box I tried running gdb
against on Thursday has 10 boards of interest.  Each running its own
instance of the kernel -- 2 instances each of 5 different versions of
the kernel.

For that machine if I want to talk to all 10 boards, then I need 10
different tcp connections -- each talking to a different gdb stub.
