OpenStreetMap
Just got back from a week of skiing in Verbier. Snow conditions weren't great so most of the time was spent on the upper slopes. My GPS (eTrex Venture) will only store 2048 points, so I had it set to record a point "least often" - I didn't take a computer with me to download the points to, so I got about 2.5 days' worth of data for the end of the week.
I've mapped the tracks I've got - lots of the upper lifts and pistes, including the black mogul run from Mont Fort (which I ended up doing in white-out conditions (!). I'll try and get tracks from one of the snowboarders in the group who was downloading the contents of his GPS every day, which should cover much more of the Verbier pistes, right down to the bottom of the Medran lift.
Sadly, Mapnik and Osma don't render pistes, although the chairlifts, gondolas and cablecars are rendered (is anyone rendering the pistes on another server? Maybe I should set one up...). I've tagged the tracks as proposed by http://wiki.openstreetmap.org/index.php/Proposed_features/Piste_Maps so drag lifts are marked as piste:lift rather than arielway.

I'd really like to see pistes rendered on the Osmarender layer.
One of the very earliest ever uses of Osmarender was to create a piste map: http://wiki.openstreetmap.org/index.php/Image:LesCrosets.png That was in the days of black and white ;)
It would be really good to have proper maps for skiing instead of the dangerously inaccurate garbage they hand out in the resorts.

Me too. I was disappointed to find my Isola 2000 stuff didn't show up

I and studerap still working on piste map rules for osmarender. I've added some previews here: http://wiki.openstreetmap.org/index.php/User:Ast/PisteMaps

Trouble is you want solid lines of different colours for the pistes, which might not fit in well with a general purpose render. Might be well suited to Kosmos, where you could add in shading and generate your piste map to taste.
