Yeah that's what I meant. To me re-using the IDL would be a big plus because then all data can always be converted from one format to the other.

The reasons you gave make sense, although I'm not super familiar with the RPC aspect of protocol buffers so that's new to me.

I could imagine implementing something like this as an alternate wire format and client library for protocol buffers. Can you outline the main reason you chose not to go this route? In particular, what aspects of the proto descriptor language don't fit Cap'n Proto? Or what aspects did you feel needed to be changed for some other reason?
