This is only a minor issue (avoidable using the non-free archive for distribution, which
is quite peculiar but true in order to avoid possible issues for people who sells CDs/DVSs 
at a symbolic charge). 
The main problem is that GDAL is not GPL and using an ECW-enabled GDAL is mandatory 
in order to use the library with grass or mapserver. 
So a gdal+ecw package is not distributable.
Also mapserver is not GPL and we had the same problem. In order to
distribute at least an ECW-enabled GRASS we need to distribute
an ECW-enabled GDAL, so we have currently no chances.

Of course IANAL applies :)
