Mac/FreeBSD shared drive, which filesystem to choose

[Timothy Luoma]

I have an external firewire drive that I would like to use both with my 
Powerbook (Mac OS X 10.3.7) and FreeBSD 5.3.

Ideally I would like read/write access from both machines.

Is there a filesystem that both OSes can read?  The only one I know of 
is FAT32, which (IIRC) isn't a good choice on large drives.

Thoughts appreciated
