We typically see seeders of eZ publish torrents around 1(me) or 2 seeders, sometimes as many as 4 on the tracker's website.
Though those numbers are rarely accurate unless a seeder seeds for an extended period of time. For example, I'll seed almost all the time on at least 1 or 2 computers or more if I can ;)
Also more seeders are seen when actually downloading or running a bittorrent application than ever show on the website.
So regulars who seed see more accurate numbers than others ...
