The Open Circulation Edition is a limited version of Xandros Desktop OS that can be download at no charge and freely distributed to others. It is strictly for non-commercial use, and no e-mail installation support is included.
If you're looking for a good Debian-based distro, this is one you might consider.
BitTorrent is used for the free download; it's $10 for the download if you want to use HTTP (to pay for their bandwidth costs).
FWIW.
Cheers,
Scott.
