Paul I know your concern perfectly because I work in IT as well (at least ATM) and some stuff which people come with to the shop is trivial as hell.
Like I was mentioning a lot of times, Vitalise is great because of it ultra high compression and compatibility with most of extensions - Big thanks to that for Yves! But at the same time it has got it's own limitations and doesn't work so perfectly like other plugins available by other middleware companies, which are promoting their plugins quite a heck. And a great games and showcases are coming along them. But it doesnt happen with Vitalise which looks like forgotten site from 90's.
I know that it takes ages to continue developing it... And I would love to see it going on but seeing how Yves was fighting with it to make it working under MMF2... And that I totally agree with Kimera point of view I also have to say pass on it... And really im sad telling it especially that I had Vitalize installed before Flash and Java... But in last years I almost dont use it at all.
The only way to keep it is to have a dedicated person working on it and providing executable sandbox like it is with Flash.
