In theory you can use cmsg on POSIX systems to send channels over channels, by treating channels as file descriptors. I tried this first, and I believe it actually worked well on Linux. But on Mac I ran into all sorts of (as far as I can tell) kernel bugs, including kernel panics and data loss. It might still be possible by using Mach ports instead on the Mac (and I started to sketch that code), but I eventually figured it was going to be cleaner to just stop sending channels over channels across process boundaries.
I guess if I get desperate I could try to get cross-process channels-over-channels working again, but I think it won't be more than a week's worth of work to do things the clean way.
