By reading from a network mounted drive - either SMB or NFS. NFS is 
slightly less bad. xine is not as bad because the Linux box is not 
using wireless. vlc on OS-X with WiFi is the worst case.

I'm not supposed to understand - it's a mystery.

Well, hopefully 802.11g is a little less bad. I was planning to sign up 
to Blueface anyway, and today's telephone bill jogged my mind, sharply. 
I was planning to buy a little 2 port ATA-SIP adapter gubbins but as it 
turns out they have a Linksys WRT854G with 2 ATA ports for not a whole 
lot more (well, less than the standalone router anyway) so I've ordered 
one of those, and I'm off to high speed WiFi land.
