Thanks for your reply.  It turned out that I did have a bug in my handling 
of transaction IDs longer than a byte, which was probably why I never 
received any announce_peer messages since the get_peers reply wouldn't have 
a valid transaction ID.  Well, technically it was valid according to the 

On a related note (if you don't mind), is there any recommendation on how to 
decide whether to track a torrent?  Currently I do it if the info hash falls 
in my bucket range, but that means I'm tracking between 400-500 torrents 
which seems a little excessive.  Is that a normal number?
