Similar to the public notebook mirrors on paws-public.wmflabs.org (provided by default in the public version of PAWS), it would be useful to be able to access other user's notebooks in SWAP (nee PAWS Internal) directly from Jupyter, probably in some sort of read-only mode.
(E.g. if I have a notebook titled "Untitled", other SWAP users should be able to view it at http://localhost:8000/user/tbayer/notebooks/Untitled.ipynb . As @yuvipanda pointed out, other users already have read access by default via the command line - but not directly via Jupyter.)
