Looks like Resolume is not really able to do this and after searching I am not sure MadMapper would be able to either.
I know it can be hard to accomodate every edge use case but if there is an extension for reading weather data why not one for reading files from a folder?
Anyways, I am going to go ahead and code this in Processing or something similar.
If anyone would like to license/purchase this software send me an email over at www.Lumenarius.com
and we can see what is possible.
