Hi, I'm part of the 0MQ team in FastMQ, we're making a free low latency messaging library in C++ and Dhruva suggested it could be useful in Boost. The current stable 0MQ/1.0 is probably too complex to use in Boost but the forthcoming 0MQ/2.0 has a simpler socket-style API (sends messages rather than bytes) and runs with no external components. Dhruva is probably better placed than me to explain how 0MQ could help Boost users. One issue we've already discussed is licensing: currently 0MQ is LGPL, but we'd be prepared to change the license on 0MQ/2.0 to BSL (or dual-license it) so it can be included in Boost. Please excuse in advance my ignorance: I'm neither a developer nor user of 0MQ, but acting as community front-end. Cheers, Pieter Hintjens FastMQ
