Would you mind to consider adding this feature to upcoming release? Copying files through "file transfer" is cumbersome: one must wait for whole file to complete AND he/she may be interested only in a tiny portion of it. I think this concept would mainly benefit those who like to play audio/video files stored at home from remote PCs, although editing some documents transparently (no fuss with multiple unsynched copies) is also a possibilty.
PS. It would be nice to have the ability to control readahead cache size as well.
