It's been one month since the ourFootPrints import was performed.
Here's a status update.

 * I imported 8,337 ways initially
 * 2.604 of these are now left untouched with the temporary tags, i.e.
we've merged 2/3 of the data into OSM proper

In our case doing this sort of shadow import where all the imported
values are given temporary tags went very well.  It's really easy for
anyone to download any area of Iceland (or the whole country dump) and
start merging in the data that hasn't been added yet.

And since the tags we used weren't known to any data user our tiles
and GPS exports were completely unaffected, aside from new & validated
data trickling in each day.

Here are some instructions on how to do that for anyone that's interested:
