I haven't picked a license (have to check that with Joshua first too), but the code ended up in an unrestricted subversion repository recently, so I might as well tell where. Beware that it's not "open source", so no using the code to setup your own site. Actually, you can't even take snippets of the code and copy it into your own systems. (Yet). That being said, it is at:
svn co http://svn.develooper.com/projects/geourl/trunk/ geourl
Before adding any new features, I'd like to get the outstanding bugs tackled first. (For example there's a bug that makes the /near/ page not show other weblogs at exactly your location).
If there's interest, I'll setup a mailing list for this...

Yes, the weblogs-at-same-location thing is bugging me too, as I mentioned in the bitflux blog http://blog.bitflux.ch/archive/2005/05/31/swiss-blogs-map.html#comments I'm using worldkit, but the problem is the same.
GeoURL source code
If there's interest, I'll setup a mailing list for this...
Yes, there is interest :-) Please add me to the list, thanks.
GeoURL is written in Perl ?
Hi,
as your posting showed up in may, i hope you have fixed some major bugs in the GeoURL source code in the meantime. Please add me to the mailing list, too - if possible.
Thanks a lot,
Thomas
