Yeah, I think that's what I want. However, if I put eggname==dev in the 
eggs option, I get a resolution error. See my last reply to PJE's last 
reply to me a few minutes ago.

I've confirmed that if I just use find-links as above and then list the 
egg name without a version spec, it does *not* try to re-download (at 
least as far as I can tell).
