This is a great idea. My two cents:

1. An accounts system would be great so that I could just run ``python experiment.py | seashells u=almostarockstar p=hunter2`` or similar with keys, and then have a bookmark on my phone to view seashells.io/u/almostarockstar.

2. A self hosted / open source option would be awesome.

3. A way to view other peoples public seashells urls would make this interesting.

4. Possible options to allow html output which could be paired with a css file attached to your account.

Can't wait to set this up with my own experiments (evolutionary computation).
