The limiting factors currently are the simplification required so the TerraGear and FlightGear don't choke on the load of details we get from the low resolution imagery ;-) , and the second is making the process workable for average Joe User (which is mainly a problem of simplification, as well ;-) )
I have documented the process of classification at http://www.custom-scenery.org/Building-Scener.331.0.html Martin is currently working on trying the process himself and maybe will be able to establish a webservice where users can retrieve parts of the Landsat imagery for their favourite area, produce a training vector map, e.g. using QGIS, submit that to the service again and retrieve automatically classified vector data. He has established close ties with the OSGeo foundation and we are allowed to use some of their topnotch hardware for this task. So, no, this is not "far" from working. In contrast, we are finally approaching a point where this can be applied generally, and it might be that Seb's work will allow us to use all the detail we can retrieve from Landsat.
