Present way of file-listing sounds like carriages being hooked up to a train, sfv becomes the head when present.
Given that you want to take flashfxps limitations into account, can a changable 'list', separate for upload and download, with sfv on top, be added to X?
If not, can the present file-listing optionally prompt a second way without a major rewrite needed?
This is what I made of it after reading things above...
