How does it sound?

Unfortunately, having to deal with ECW is not a matter of being maniacs
of proprietary formats but of many useful free geoinformation provided in
ECW format. Actually, not having ECW (or mrsid) support can be a cause
of not using qgis at all.
What about designing a separate external tool that

Micha,
I'm also using ECW and share your concern but on the other hand who knows
when ERDAS is going to take a decision or even if they are going to
take a decision
at all?

FWTools has too many other functionalities, I refer to something like

The problem is the *: is there a public wavelet compressed format?
