1. Passing open file descriptors
Use /proc/*/fd/* - you can pass the pid and filedescriptor number as
text, and have the other process simply open the descriptor. This
assumes that both processes are running as the same user.
This appears to work for network sockets and named pipes as well as
for files, under 1.1.69.
I wouldn't wait for the streams stuff, it could be a while coming.
