- Some of them (like uDig) are LGPL, not GPL.  Does this make a difference here?

- I'm guessing they probably don't "include" closed software, but are just _distributed_ with it.  They are probably linked against GDAL (which has an MIT license), and distributed along with a GDAL plugin which is linked against the main GDAL library and the ECW libs.  I don't think ECW support is normally built into the main GDAL library.  I'm not sure what aspects of this are relevant ;)
