I have done this frequently.
In my experience the only way is FAT32, for large drives you need to 
compile the freebsd kernel with the MSDOSFS_LARGE option.
You should be able to read/write the drive in OSX 10.3 and upwards, I do 
not think it works with 10.2 and 10.1
Formatting the drive is easy in OSX so I would do it there
I beleive the reason for UFS not being compatible is an endian (big vs 
small) issue, maybe solved now with the new intel macs.
I have not tried it with usb, but it worked with firewire.

If both machines are connected through a network you may also want to 
take a look at netatalk
