[Nottingham] Shared filesystem

[Joe Wrigley]

Scenario:

I have a dual boot laptop with Windows XP and Gentoo Linux. I have a 
partition I want to use for data which I have been using to share data 
between the two OSs. I would like to be able to mount the partition on 
/home with useful permissions. A FAT derivative doesn't really fit the 
bill, and ext* isn't supported in any low-level way in windows 
(explore2fs can be useful, but I want something that works in a more 
"native" way). Is there any file system that can be used by both OSs, 
more useful than FAT?

Thanks,

Joe
