Magnetic: Firewire didn't used to work OOTB in Linux or from what I
could tell a few years ago, much of any other time either. I never
got it to work correctly and I spent LOTS of time trying. I'm glad
they got it going now though.

Also, firewire is not dead-nowadays even alot of cheap clone PC mobos
at my local computer store have firewire on board, or if not, the
cards are sub-$15 if you know where to look, about $30 if you don't.
All decent camcorders still come with it. And by 'decent' I don't
mean the current crop of DVD based things either..

Also, firewire is preferred in the audio and video worlds because it
gives guarantees of data transfer accuracy that USB does not. Firewire
times things much more precisely than USB. Both standards will be
around for a long long time.

With that said, I have several firewire devices around and would be
happy to help test with them. A JVC GR-DVL915U miniDV camcorder, a
Que-Fire firewire CD burner at 24x. I can get a variety of other
firewire enclosures used for $10 or thereabouts, and stick in big HDDs
etc. Potentially, I might also have access to some real high-end
video equipment and a firewire audio mixer (sorry, the make escapes
me, it's a friends but he's got fat broadband and would let me come
over and plug it in.) Also an iBot firewire camera. It has great
quality, actually.

Finally, WRT the USB2, isn't that a Chris Hodges thing? Or is someone
else just adding the 2.0 support to Poseidon for him? DOesn't make
sense to re-invent the wheel for something we already have which
works so well.

Do I have to sign an NDA or something?
