I don’t own Catalyst and their website seems to be mostly broken links, so I can’t find much information to give any definitive answers, but…
If they let you play Quatz Composer files and they don’t use “safe” mode to do it, then it should work. If the .qtz works in other applications but not Catalyst, they probably use “safe” mode which forbids the use of 3rd party plugins. I think there’s a Kineme plugin to work around that restriction, but that may introduce its own set of problems…
I’d ask the Catalyst folk, and request native Syphon support while you’re at it.
