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

[Matteo]

Hi Brett,

yes, I have checked Zyre extensively, the first draft was using Zyre (years
ago), I actually thought about sending a patch for Zyre to add some of the
things that I wanted but I ultimately decided against it - the reason being
that it would have gone against what Zyre was developed to do and I didn't
want to pollute it with my specifics.

You could very well use Zyre via IPC to solve most of the problems I have
faced in my project, heck, if they would have chosen Zyre instead of D-Bus
I wouldn't be here to talk about it.

The reason I moved away from Zyre:
Zyre is built for LAN/WAN - it can be used with IPC but it would be
overkill.
Dependencies - Zyre brings in more than I really need and because I need to
cross compile this in Yocto, the less the better.
iNotify is just a simpler way to do what I needed to do - Again Zyre's use
case was much more complex and its solutions follow.
Protocol, Zyre adds HBs, threading model, membership, etc... Again,
different scope

Could I have done it in Zyre? Absolutely
