Just because you hackers have cobbled together some bizzare way to run IE on Linux doesn't mean that it's completley legal or intended. Although I'm certainly not surprised you wasted effort massive amounts of effort just to run something you claim is inferior simply because you don't have to pay for it.
Completely legal, if not I would never have done it (though I no longer needed it after one of our internal apps started supporting FireFox).
As for intended, the point is *MS gives it away*, hell I have a copy running on my Mac which was given away by MS.

I have not contributed code to the WINE project, so my 'effort' was installing wine (clicking a link in the web browser) and then just running the exe to install ie. I did it because one of the apps we had purchased through a vendor did not work right on FireFox. They corrected the issue and IE is now gone on my box.
