multidownload.... why just 10 segment?

Well it won't be exactly as torrent.

You'll depand on lots of open connections (killing Your own or ISPs routers) while good torrent clients don't need it. So don't forget to remove 1,2KB/s (as far as I remember) min download limit for segmented downloading coz You'll need it Torrent clients connects to different users to get parts, while DC slots are "permanent" (unless You get disconnected under some conditions). Maybe it would be good to (experimentally) implement a slot rotation system based on waiting user queue size?

(I was thinking to do it some day - just lack skillz)

Part distribution is also very important here, and even clents like ApexDC++ or SDC++ misses a lot to torrents.

Still it may be worth to experiment as long as it remains a non poublic experiment. And You'll need to convince a bit of people to get some reliable test results.
