One possibility-- consider writing your own resource loader, using the FileResourceLoader as a model. If this resource loader caches based on filesystem location you should be able to maintain Velocity's performance.
Instead of configuring the resource loader class via properties, use dependency injection. (required version 1.5). Using Spring to instantiate your resource loader configured with your dynamic path info. Then pass the live resource loader into Velocity when initializing.

Thanks Nathan. I did post this question on the Spring Forum first but got no response. Since I cannot seem to do exactly what I want I am using what you are calling a pathfinder. The thing that sucks is that I need to change the returns from all my controllers and than the includes inside all my templates. No stress here though. I have a work around. It just seems like bad form and in the long run will potentially be harder to maintain. Again, thanks for the response.
