This NSWorkspace category allows you to discern between mounted physical volumes and network volumes. Please note that currently only webdav volumes are recognized as network drives, however this can be easily fixed by simply adding some string comparisons at the end of the -isNetworkVolumeAtPath: which the desired network volumes.
