I may have worded it badly… I'm sorry.
I should've said s/server/service/. I already had JigdoFUSE working
(being able to assemble images correctly, though not very efficiently)
by the time I discovered jigdoofus. The problem is I only have
FTP access to a free server without ability to mount filesystems now.
I could host the service at home, but my uplink would not suffice
for that purpose. I could also rent another server (VPS?),
but I don't know if it is worth to.

I have other ideas though. In a world closer to perfect,
users would just use jigdo to get Debian. In the real world
though, they usually don't bother to install a separate program
just to get an image. They may already have a BitTorrent client,
but I presume not all images are seeded. For BitTorrent there is
BitLet – a Java applet which downloads a torrent client-side.
It should be possible to write a similar applet for jigdo.
I think even reusing existing packages/CDs would be possible then.

For those who don't have a Java-enabled browser, I think
a PHP (*flinch*) script could be used to assemble images
on-the-fly enabling the ability to download them via HTTP.
The script could be pushed to package/jigdo mirrors to turn
them into CD mirrors. Correct me if I'm wrong, but I think
such mirrors could be used as webseeds for BitTorrent.

I'm looking forward to hearing your opinion on these ideas.
If you think they're worth the effort, I might manage to save 
some spare time to implement them.

Best regards. :-)
