HI Pieter,
Thanks for your reply!
XPUB \ XSUB looks good for me. I can certainly use an XPUB to detect a new
incoming subscription. Quick question though... Must XPUB\XSUB be used at
intermediate layer? Can final endpoints be XPUB\XSUB? I don't want to add a
proxy layer in the middle.
Also not sure how the XSUB will detect if the XPUB on the other went down? (I
am assuming here that XPUB \ XSUB can be used as endpoints).
Some sample code will definitely be helpful.. I already look at
tests/test_sub_forward.cpp

I think both these could be done by a pubsub device (separate process
or embedded) that uses XPUB to detect new subscriptions, and
heartbeats to signal publisher activity (and turns these into EOS).
Perhaps a useful example for the Guide. If you need this urgently,
contact me off list and I'll put you in touch with someone who can
build it for you in exchange for cookies.
