can you give us some pro's and con's of this method?
does it work with dynamic objects? I dont see any in your demo.
if not, I think some recent methods like refective shadowmapping, caustic mapping might do a better job....

What format would be best for you? We tried to use one that would be
happy on Windows, Mac and Linux equally :).

Here is some darkening via indirect shadow:
And here is some under the corridor:
There is no artist intervention required of the form you suggest. You
literally point the loght at coloured objects and magic happens. No
artist tagging required.
Using Tomcat but need to do more? Need to support web services, security?
