[zeromq-dev] New project: Bacaro - a Message Bus for IPC based on ZMQ

[Francesco]

Hey Matteo,

Just wanted to say that the project looks very interesting.
And I'm also happy to see something new being based on zeromq!
I think zeromq is still very useful in a number of scenarios... the project
lacks energies and community involvement unfortunately.

Cheers,
Francesco
