Hey, sorry for the late response.

Regarding the caching. Right now there is no dedicated caching policy, you can think about current caches as temporary files. Since it's impossible to download large files (like FLAC) into memory and I didn't want to block HTTP connection, I'm storing downloaded files into application cache folder(NSCachesDirectory). So OS will manage this caches for us, it will be cleaned once system requires resources, this process is totally nondeterministic. If you want to implement dedicated caching strategy I recommend to take a look into NSURLCache.

About nodes and constructing graphs. I just pushed small change in b943430, which adds new method- (void)playUrl:(NSURL *)url withOutputUnitClass:(Class)outputUnitClass. You can subclass ORGMOutputUnit, define your graph there. Example implementation can be found in ORGMOutputUnit.m (which is default output right now), it is basically simple OutputUnit for Remote I/O node.
