Agree.

I'm afraid yours hopes are invalid.  Those checks are here,and really are annoying.  Itw had adapted 
them on its own way, and so it have its own ways how to get rid of it (more levels or 
verbosity/security/checks, different mechanism on remembering of already clicked yes/no (based on 
regex, so you can get rid of a lot)
In 1.6 this was little bit glued together, in 1.7 this was rewritten. You can even redirect 
"YES\nYES\nYES..." to stdin of javaws to walk around it completely :))

Indeed it will have windows support. In all cases, it will be heavily experimental as my windows 
abilities are very limited.  In all cases it will be some beggining, andhopefuly the windows port 
will grow in right direction.
The binary release of ITW for windows will not be capable of  registering the protocol (no msi, just 
zip), however any redistributor, will be bale to pack this blob and wrap to msi or whatever 
suitable. (note, this may change, it is still some way to walk before release)

Also src release of ITW dont have any url registrations, but to RPM for fedora I'm maintaing, I will 
add it (thank you for hints)
