[bittorrent] BT for serving smallish (3MB) files

My company has an application (http://www.goombah.coom) that uses 
BitTorrent internally to distribute some largish (50MB) data files it 
needs to pass around. (The  app is written in Python, if you're 

This is a music recommendation app, and it allows users to acquire 
(legal) music files. This are typically much smaller than the files 
mentioned above -- they tend to be in the 3MB size range. I have heard 
it said that BT isn't worth it for files less than 10MB. But, we would 
like to get the load for serving the files off of our servers and 
spread among the clients.

So, a series of questions:

1) With 3MB files, and many people downloading each one at once, is 
there  still significant server bandwidth using a BT tracker compared 
to just serving the files? Does anyone have any statistics?

2) How well does trackerless BT work at present? Under the 
circumstances laid out in (1) above, what would the pros and cons be? 
It seems that, at least from the perspective of our server load, it 
would eliminate the question of whether it would be worth it to use BT 
for files < 10MB, since there is no tracker load.

Many thanks for any help anyone can give with these questions.
