It would be great if there was a way to share one database. However, I see
problems there and possible fights over data. Here's my suggestion for a two
database solution:

There are at least two methods to move data from OSM/PD database to
OSM/ODbL. I doubt that the other way (OSM/ODbL -> OSM/PD) will be possible
after the new license is effective.

1. Contributors upload PD GPS tracks and both can use them to create
features. - This is already possible.
2. Any feature created into OSM/PD can be easily copy/pasted into OSM/ODbL.
- I tried using two layers in JOSM and it is possible to copy features from
a layer to another. For some reason, the coordinates were not copied, e.g.,
manual positioning is required at the moment, but that would be easy to fix.

I know that #2 won't work for everything - ways connected to other ways,
relations or adjusting node positions.. but it will work for completely new
features.

We could also create tools, which will work on two layers at once. Move a
node in PD version and ODbL version is also affected..

So, technical solutions exist to help people to maintain two databases.
There will always be more work, but it works and it is clearer.

Any other ideas how the two databases could be linked together?

Or how to solve the 3 issues for keeping one database?
