Good points. Thanks.

Null-separation works well with find and xargs and not-so-well with pretty much
everything else, no?

I've been thinking about this for a while but I don't see any easy solutions.
(Other than saying "screw it; let's go with Plan 9...")

Is this:

   http://tools.ietf.org/html/rfc3987

still your recommended reading?

My main goal was to produce directory names that are 

   a) fully determined by the activity metadata, 
   b) vaguely human readable, and 
   c) shell-friendly 

from whatever crap I'm handed. 

My further thought was that smarter viewers like the Journal would use the
authoritative data in the .xos/metadata.json to figure out how to render the
session.

Regards, and thanks very much for your comments,
