Interesting! Did you own all of the systems? Why did it fall down
to one system?

Multitracker might be simpler to implement but it has two big disadvantages:

 - You must tell people to use the *correct* tracker-list while creating torrents
   This is easy in a private environment but won't work for an open tracker
 - Old torrents won't know about any new/dead trackers

The DNS version will 'just work' and isn't that complicated: ~30 lines of perl code
should do it. Handling strong/weak systems also isn't hard: The DNS just
has to return IPs of 'strong' systems more often.
