Is this is a suggestion for a way to change IPython notebook itself?

For  IPython users:  If you start an IPython notebook server (say in
python mode) and try to open a notebook with backend:'julia', would it
just give an error and tell the user to run another notebook server
with a julia backend?

For SageMathCloud users: I can write code to start several notebook
servers, which run simulaneously, I guess, assuming their state files
don't conflict.
