Oh dear; hadn't realized this was an issue.  We installed Twisted and 
Cyclone from source.

There is a debian package for twisted (python-twisted), but not for Cyclone.

The issues below are pretty straightforward.  This one seems more of a 
problem.

We probably don't.  We just jumped off of Sathya's first pass, and 
didn't play with the Cyclone details at all.

No, those are old versions and will be completely replaced.  We'll 
follow your approach for these handlers:  use the query parameters to 
determine the fingerprints of routers that match the parameters, then 
just respond with the corresponding JSON files from the filesystem.

Hopefully we'll have an example of one of these that should enable one 
to plug in Sathya's new back-end without modifying the handler classes, 
just the database module.

Correct, that shouldn't be there.
