Neither the tracker nor seeding the torrents generates noteworthy load
on the server. It has rather conservative settings when it comes to
the number of concurrently seeded files, and not too many people
download using the torrents.
And as you said: The swarm supports itself, reducing the load even
more, in those cases where a torrent is requested by many people.

We have the spare bandwidth on the server, and it doesn't conflict
with pushing to the mirrors either (as it only sees the new torrents
when the files are made public, i.e. when the initial set of mirrors
already do carry the files.

:-) - you do need someone to start seeding - otherwise you only have a
file that says "byterange x to y has checksum a, byterange w to v has
checksum b, ..., other peers gather at <tracker>" - then the client
visits tracker, sees the other peers that want the same file, but
nobody offers them. So you need to get one copy out into the swarm -
and that is mainly the job of the client setup on bilbo.
(again I exclude the webseeds here, so in theory a random client could
start by downloading the file using the webseed and then seed to the
swarm. But as most users have ADSL and their upload is comparably
slow, there /should/ be a box that can seed fast)

But

I already did so some time ago - it is in our internal git-based
documentation-setup. Configuration seems huge, but that contain all
the default values, so don't be scared :-)
