I share this concern.  We need to support people who can only pull 
information to their machines infrequently, not whenever a script on 
the system decides it needs to fetch something.

Maybe there can be a local cached copy, and then the script can run 
around (right before doing the checks) and see if there are newer 
versions on the net, in the ports tree, manually updated from a file, 
etc.  Clearly the cache has to be revalidated with respect to its (pick 
your favorite cryptographic checksum) signing.
