My conax CAM refuses to decrypt more than one stream, but this is CAM 
dependant, as the specification (EN50221) says that CAMs should (or could) 
support this. Please search the archive (*) for confirmation that this will 
work with this CAM type, if you do not find anything, the only method would 
be to by some hardware and test it.

Well, depends on what you define as support. More often than not, the answers 
you would be seeking is answered in the archives (*) at least for the 
drivers. If you are so unlucky as to find a BUG, a bugreport to this list is 
usually resolved pretty quickly. For software problems, it really depends on 
the maintainers around it rather than LinuxTV. As I mentioned earlier, my 
Nexus-S has been working great for ages, except that rare arm crash bug.

If you are looking for commercial support, maybe Convergence would be 
helpfull? http://www.convergence.de
