I have not tried this IDE myself, but unless VA knows about this IDE, and has been written to support it, then it will not show up or work.
If the release of VS2005 is anything to go by VA will not support the IDE until much closer to the release date. At this point the IDE is likely to be undergoing significant changes that would impact VA's ability to work correctly.

A little over 6gig in total
Strangely enough I am not rushing to do a 6gig download right now
