I don't think our only options here are immediate adoption and relative chaos. Here's what I would like to see: Quantum, cinder, and ceilometer get together, recognize a shared need for rpc, acknowledge the successes and failures of the nova.rpc library, and create a better implementation with eventual adoption by Nova kept in mind. Doesn't that sound better? This approach seems much nicer to me, because I believe that code reuse is likely to be detrimental unless the code we're talking about was created with reuse and generality in mind. Since I find that suggestion implausible regarding nova.rpc in particular, I think we will do better overall avoiding its wider adoption. Please, forgive me if I'm being drawn in falsely by the allure of better code. Code structure and quality *is* something I obsess about. But I appreciate the need to be practical in the short term as well, if I am not always the best at articulating it. The agreement from various quarters about the problems with the current nova.rpc gave me hope that we could craft a better rpc library without too much delay, even if I myself can only contribute in a small way to that effort.
