[IPython-dev] New IPEP for a multi-directory notebook in IPython

[Matthias Bussonnier]

How does this integrate with db back end ?
I know url that reflect notebook location seem great, and useful in most
cases, because server run local where server is. But it is causing
confusion, especially with the /files handler.
