At this time, I don't believe so.
According to the manual, under "More Effects";
For audio, Resolume supports VST plugins.
For video, Resolume supports FFGL plugins.
File types: .dll (PC) or .bundle (Mac)
If you wanted to add more effects, they usually go into the Extra Effects folder under Resolume in your Documents location.
You may want to look into Syphon(Mac), Spout(PC), NDI depending on what you're trying to do.
