Sorry for my previous post, i didn't really get what you wanted, OP. Anyway, Boxee can handle samba shares right? (At least XBMC can, and as far as i know Boxee is based on that)

If it can, you can try to install tinysmb and tinysmbgui from extras-devel (so, be careful there). I have to admit i never tested this, but this is what i would try in your shoes.
