But why not just use an http: URI to do that?  You don't need the small
database at all.  Something like

	http://schemers.org/R5RS/TinyCLOS/rationals/foo.scm

The database could be stored on the server instead of having a local
copy everywhere.

Even with the http: URI you could still use a local database.
