Hi,
Tactile paving is of course a reason to map and it seems to be used also in OSM.
"Virtual" as an key or value seems not in use yet at all: * http://taginfo.openstreetmap.orgtags/highway=virtual * http://taginfo.openstreetmap.org/tags/highway:virtual=pedestrian
Unfortunately all more well known routers currently don't support any virtual attribute nor pedestrian/bike area routing. At least they are aware of that: * Valhalla: https://github.com/valhalla/valhalla/issues/42 (nice comment uf Züritütsch). * OSRM: https://github.com/Project-OSRM/osrm-backend/issues/64 * Graphhopper: https://github.com/graphhopper/graphhopper/issues/82
So even if we would add highway=virtual, the routers would not recognize that. In fact, some routers discourage (like me) to add e.g. highway=footway (nor highway=virtual) by saying "do not map for the router!" (see OSRM issue 64). I'm unhappy to see non-existing ways in OSM, and would be very reluctant to add them.

Of course, I remember http://wiki.openstreetmap.org/wiki/Key:tactile_paving . Other tags maybe available too.
