I tried xz... but my mesh2 inc files are still about 80 MB after 
compressing - so I will still need some 700 GB of webspace make them 
available for download. I recently did some research in webspace prices 
- and found out that 2 TB would be MUCH too expensive for me, as they 
usually are around 500 US$/year... the largest webspace offer I could 
afford is 500 GB for 36 euros/year, and that probably would be not 
enough for all 8000+ tiles processed into compressed mesh2 inc files.

Most likely, I would store the POVEarth terrain data online as PNG 
heightfields - they are smaller than 10 MB per tile down the line.

However, I cancelled my "rock-o-data" webspace (hosted by the very same 
company which offers that bargain 500 GB), which will expire in November 
2021... after that, I'll migrate the POVEarth data to a new webspace 
under povearth.de!

Did not try out yet; first, I'll have to (re-)calculate the mesh2 from 
the n80e017 data tile, then render a few views and also trying to do a 
first multi-tile scene (from n80e016 and n80e017 tiles)... and finally 
get some hours of sleep! ;-)

See you in Khyberspace!
