I had a nice big rant, because this really ticked me off but I'll bring it back 
to a few fairly simple points. 

1. This is not about throwing money at a problem. It's a legal quibble problem. 
After that it might be a money problem.
1a. More importantly, for the *user* this is about removing easy access to a 
feature. (Translation: It's a regression).
2. This an option, but the plugin still needs to be there.
3. The ECW Project Manager has been asked for an opinion (the PSC has a copy), 
and I do not see this as incompatible with OSGeo4W continuing to provide the 
ECW plugin.
4. My major data providers do not yet provide Jpeg2000 as a standard option. 
This leaves me with options of an ECW which can probably be processed one day 
and emailed the next; or any other option which will go on a hard drive and the 
postal service will sit on (or kick around) for a week before it gets to me.
5. Yes, I agree they're bad. But there's a heck of a lot of legacy ecw around, 
particularly in Australia. (There's a lot of doc and docx around too)
5a. GDAL does a much better job of turning ecw into something else than 
anything else I've seen. But if ecw isn't accessible, then the data is 
effectively lost.

It's not just up to me. It's also up to QGIS to work out what sort of uptake it 
wants. Particularly here in Australia there is a *lot* of existing ecw, for 
example at the first Australian QGIS forum, ECW use ran at around 90%. It will 
make it extremely difficult to show off QGIS if it can't be easily shown to 
handle their existing data. Once we have the foot in the door then we can start 
the weaning process.

-ramon.

In case this triggers the "don't say anything bad" email, I'm writing this from 
my involved *user* perspective.  I'm also writing in a QGIS advocate sense. I'm 
not meaning criticism, but I am meaning to express serious concern that this 
one decision will make both my life as a user and particularly as an advocate 
in Australia much harder.
