The ECW driver for GDAL can be built as a plugin,and sit
in non-free.  There is no current package for an ECW driver
as a plugin but it would be reasonably easy to create.

However, I suggest we wait to package the ECW SDK till 
after the ECW SDK 3.2 (?) release which is supposed to be
coming up shortly.  It should be altered to use an autoconf
mechanism for building the ECW library, and thus be easier
to package.  It also contains some fixes not in the last release
that are quite significant for Linux.
