Cool! however, I would rather avoid having to manage kafka, if something
simpler exists :-)

I know there is also a mature zeromq client so given I already have the
persistent part, I could probably leverage that but I thought somebody
might have already treaded that path...

Thanks a lot for the pointer, anyway.
