Director has its Shockwave3D ... but not everyone uses/wants to use Director. iShell is a valid alternative (www.tribeworks.com) that already supports Pulse3D. As iShell's target is to provide a more flexible, more efficient and less expensive alternative to Marcomedia's Director, why not check out a possible integration? iShell is Mac/Win.

just an idea to get a bigger community by delivering added value to other platforms.
