I think the idea that everything only touched by PD contributors is PD
data is easily good enough. It would be a tough sell to say that
because your road is next to my road, I have intellectual property
rights over the road you drew. (Especially since facts can't be
copyrighted in the first place).

My motivation is a bit different from Landon's. I want to make a map
could (eventually) be the authoritative world map which people use for
absolutely everything mapping related. I think the new license is
fantastic, but the whole fiasco has made me one of Those People; who
would rather PD his data than waste time arguing about legalese for a
not-for-profit project.

That was a great initiative. I also hope to email a lot of the
contributors (particularly the larger contributors) once we have
something up and running to ask them to public domain their work. I
think a lot of people wouldn't mind sharing more. Once its all set up,
I imagine mailing people with a short paragraph of text, a link for
more information and a link they can click to donate their data.
Simple.

Brilliant. I hadn't thought of that.

Speaking of which, are there currently any good merging tools for map
data? I foresee the need to merge map data together a lot both OSM->PD
as people PD their work and PD->OSM as the PD maps fill in areas not
covered by OSM.

In the meantime, we probably need to set up our own independent
software stack (initially using the same software, but with a
different data set) and then write tools to scrape together PD data
for the initial import. We'll need a project name (freemap? planet
map? terra mappa? wikiglobe / wikimap? The Street?) and a mailing
list.
