I've not revisited 9p in general in a while. Still hoping to get a native Plan 9 box up and running somewhere that I can play around with.
I do want to get back to this project though. Every once in a while, I look at things like Facebook's Thrift, or other RPC mechanisms that are meant to be language neutral, and I think "this could have been 9p". It's interesting to try anyway just to understand the limitations of one thing vs another.
