so in my opinion you should contact the companies involved with MrSID and
ecw to change their licence in some sort of dual licence like other
companies did (e.g. Trolltech, MySQL). After all they are interested in
widespread use of their technology - so they should open up and change
their licence so it can become a regular component of gdal/ogr. Otherwise
I don't see an easy solution.

An alternative would be to ask the data providers for their original data.
I am sure they have their data somehwer available with lossless
compression - they wouldn't throw their originals away - would they? Both
MrSID and ECW are lossy compressions ...
