Nice, few comments (based on my previous uses of the GDAL TMS mini-driver):
- your plugin should make sure the loaded layer is assigned the proper
projection (mostly pseudo-mercator); failing to do so will leave must users
unable to understand why the TMS rendering fails
- that would also switch OTF reprojection on when needed
- consider adding TMS of the Global Forest Change (see
http://www.earthenginepartners.appspot.com/science-2013-global-forest for
data source, and

in-QGIS example)

The GDAL TMS driver is in many ways a superior solution to OpenLayers; it
works perfectly fine with the multi-thread rendering, can be exported via
qgis composer, caches the tiles, etc.
