To be fair, there was nothing similar available when Christian started SIP,
and he really filled an urgent need for many glider pilots in the alps. Also
the quality of the data (presentation, updates etc.) is second to none, and
the price (19E for the online version I think) is not prohibitive to any
glider pilot in central Europe. I think it would be great to have this
information available in XCSoar, but respecting the copyright on the
database is not only a legal question, but also a matter of common sense for
us pilots flying in the alps. If this data was widely distributed without
paying for it, it would not be available in the future. 
Still, I see no reason why one could not buy membership, legally download
the html files and extract the data for use in XCSoar (maybe with the help
of some tool). 

There are other sites (http://www.landewiesen.at/map_nav.html), but they are
not on the same level with SIP. If this changes with the help of thousands
of XCSoar users - great!
