I'm working on that...
I'm allready working on rel2 of this... (iTunes opens with the new one).
It's been delayed for a couple of weeks though because my cpu of my laptop kind of burned...
Fortunetely I have insurance still on it... (it's back to the shop for 2 to 4 weeks).
However iTunes seems to need a little hack in order to sync...
I don't know about all MP3 players though...
But using the iPodSupport.kext as SBC device copying onto the MP3 (and reading from) goes much better and faster.
Work in progress thus...
