There's also UDF which doesn't suffer from a lot of the issues the
FAT16/32/32x does on large-ish devices.  FreeBSD, Windows, Linux, MacOSX
all support read/write to UDF, although it may depend on the OS version for
Windows (I think XP needs a 3rd party driver).​​

I've used UDF successfully on USB drives, although I don't think you can
boot off it.
