[R-sig-Geo] Access WMS (and alike) services from R?

Actually had found this
http://www.gdal.org/frmt_wms.html

My idea is using qgis for the interactive selection of the wms
service, layer and window, and then
make the xml and request the layer in R.

A bridge between qgis to R for raster layers, similar to the no-longer
working manageR plugin for vector layers,
would be another solution, but would imply writing to disk a raster layer.

Unfortunately cannot do this myself, trying to find an interested ms student.
