When I have 9 seeds and 200 in the swarm what does that
mean?  Is there
any way to convert those in the swarm to a seed?

I /think/ that the swarm is people with partials.  when they
finish
they'll be seeds, and in the meantime they still seed but
can't any
service 100% of requests

AFAIR anyway.

It's also possible that the tracker/client only takes 9
points to pull
from, and it's just telling yo uthat there are 200 of them
that it's
choosing from.

I'm thinking the first, but I don't see swarm on my
interfaces :o

That's right.  All swarm members can send out the file
pieces they
have.  Once a swarm member has pulled 100% of the file
pieces it is
automatically promoted to a seed and does  sending only.

I think the tracker tells the downloading swarm members who
to get the
pieces from they are missing.  So the tracker keeps track of
which
pieces of the download each swarm member has.  When a swarm
member
wants to download a new piece it asks the tracker who to get
it from. 
The tracker can tell it to get it from another swarm member
with a
partial download or from a seed.

BTW: BitTorrent etiquete is to stay connected to the swarm
after you
get promoted to a seed long enough for you to upload 2 full
copies of
the torrent.  The BitTorrent client should show you your
upload/download percentage.  When you hit 200% you should
feel free to
drop off with no guilt about abusing the rest of the swarm.
