just found your talk via google.
My name is flip and im the guy behind http://www.nas-2000.org
the NAS comes with daapd by default so an update
to firefly would be quite interesting for me/us even through the
firmware is currently in a alpha state.
Since tinky (the firmware) got ipkg support it should be easy to
create a firefly pkg.
If you are interested feel invited to the mailinglist
