Well, I have currently some issue in subscribing the forum (maybe the
confirmation request is eated by anti-spam measures on murphy), anyway
the most relevant post is


Where Tom Lynch reports:

Some examples of use cases of the SDK under the "Public Use" License

used as a GDAL driver - no problem here

used as a GDAL driver in a FOSS project like MapServer - no problem

used as a GDAL driver in a commercial, closed source product - NOT OK
(would need to use "Free" or "Commercial" licenses and the product would
 need to meet the additional requirements of these licenses)

used as a GDAL driver in a commercial, open source product - may or may not
be OK, depending on the situation.

So AFAIK the current almost-free licesing is not perceived as an issue
by ERMapper folks. Unfortunately, I still think GDAL MIT license is simply not
compatible with the GPL-compatible license. Which renders
undistributable also pure GPL sw which use GDAL as their inner engine.
