I can get you stderr and stdout mised together, not in separate files:

0G"ryG:new
"rp:%!ruby

This yanks the entire buffer into register r, opens a new window, pastes
register r into the window, feeds the entire buffer into ruby's stdin and
replaces the buffer with what the script writes to stdout or stderr.
Unfortunately, I don't know how to distinguish between output to stdout and
stderr. Since you are writing the script, however, you should know which is
which.
