i remember chatting about this a while back and unless i'm going crazy i'm sure mouser wanted something similar (i can't find the post anymore when i search).
'amorak' will allow you to add 'bookmarks' to a track whilst you are listening to it in winamp (i can't say if it works with anything else).
so, if you want to add placemarkers to your audio books or long mp3s (i need it for things like old tangerine dream tracks so i can get straight to the decent bits) then use 'amorak'.
i would have liked it to be able to halt a track at the bit i don't want to listen to but you can't have everything.
