I sent the code for zipdy-openacs that James Shannon (see
https://openacs.org/forums/message-view?message_id=28600) and I threw together a while back to Tammy. No tcl or www pages, just the distance calculator and supporting cache table/procs.
This used to be in new-file-storage. If anyone wants it, or if it's wanted in contrib in cvs then lemme know.
