First thanks for making this available!

Regarding only using the SRTM data, there is a 50m resolution dem available for Sweden under ccby4 (the “GSD-Höjddata, grid 50+” data set) if that is of any use. I believe there are something similar available for Norway.

What licence are they using for the DEM data? I only see copyright in the meta data.

Oh and in http://geoserver.org/ it is not to hard to serve geotiffs as wms directly.

Great minds think alike =)
I have been doing the same things with a Old Swedish map series, ekonomiska kartan.

But I use python for testing, as staring a server is a one liner, just run "python -m SimpleHTTPServer 8085" in the tile directory root.

Loading tiles in potlatch works great, even when giving it the url "http://localhost:8085/!/!/!.png".
