Ah, yes. It sounds so simple. But I've been perusing the various
references available (bittorrent ones are sparse - no man pages) and if
I want to seed beginning with the ones I've already downloaded, it seems
to get more complicated. Port forwarding through my firewall, generation
and publishing (I currently have no http presence) of a torrent file,
getting one of my computers to the DMZ (I use IPCop and right now all
are in the green zone),... In fact, the /usr/share/doc bitorrent files
say I need to start with a tracker.

I presume this assumes I'm downloading originally. Then, if starting in
tracking mode, how does one switch to "trackerless" or DHT? From reading
some of the refs in other posts, it seems that I would need to be
downloading from a client that supports the DHT schema. Meaning that
when I start downloading, my presence is added to the hash (or is it
routing?) tables and forwarded to peers in the network and I would have
to receive them also. Does the service CentOS is using support all this?
I don't know.
