I saw this on ebay looking for a used Nitris for a client. It is NOT my product, but I thought the forum would appreciate it.
I saw a demo of a Mistika in SoHO, UK a few years back, it was pretty amazing. The company has been plagued by a small user base and its inability to break into the post market already dominated by Autodesk and others. It also used to be Jaleo!! Remember that comp system?
Anyway, I think systems like this can do everything that is needed. If you can learn the interface and learn how to use it, its features make it a pretty amazing hero box. Better compositing and painting then iQ Pablo, Color Correction as good as Lustre. can't edit that great, but everyone edits on FCP/AVID and exports an XML/EDL anyway.
