I would like to request an option to import data from any arbitrary file into an existing download.
The option would not be available until hashes have been acquired for the file. But after that you can right click on the file and choose import - this would read in the file and locate any completed parts and slipstream them into the file (i.e. merge any currently completed parts with any completed parts from the other file).
And if it could use AICH for detecting completed (or assumed completed) parts that would really be wonderful.
BTW: Is it possible request hashes for a file from a peer without waiting in line to download actual data for the file?
If it wasn't obvious, this feature is to be able to take over a partial torrent download, and attempt it in aMule. (Well a file from any source actually.)
