Bobo,

I'm sorry I haven't replied to you sooner, but I am quite busy lately. I am still in the process of writing some kind of IP-forwarding utility for win32 -> empeg over USB.
I'm planning on releasing something usefull at the end of march. You could also ask jazzwire, he is also developing some USB filetaxi program for win32; do a search of 'filetaxi' and you will find some relevant threads...
BTW : PPP over USB on linux should be quite simple... look at the emptool source to see which device file is opened and start pppd on both sides using the appropiate device files...
