[zeromq-dev] clustering and web client recommendation

[Nikola Radovanovic]

Thank you.
I would like to make a custom-tailor message-broker, since it has to sit in
between clients (console and web) with some load-balancing and LDAP
backend. We already have some glimpse of it, but using cherrypy, which does
not seem efficient enough. Also, for some pet-project I am working on, I
would like to have something similar: REST-like service acting as a
backend for javascript frontend.

Kindest regards
