I think there has been someone who has implemented a WMS driver for GDAL
for their internal use, but I gather it would have been substantial work
to clean it up for general use.

I think it would be pretty easy to implement, given the WCS driver as a
guide.  But I don't have any client interest in it at this time, so I am
not actively pursuing it.

The main challenge with WMS compared to WCS is that it is very hard to
establish the nominal bounds and pixel resolution of a WMS service which
we need to represent it as a GDAL dataset.
