[Sugar-devel] Good filesystem for USB flash with compression?

USB flash drives have controllers that do wear-leveling. They try
really hard to make them look like hard drives. JFFS2 works on raw
flash, so it's not useful.
Basically any FS that works on all the OSes you need. ext2 is a good
option. NTFS might be, but it's fiddly.
I've tried to get a UDF filesystem on a flash once, since UDF is
supported on any OS, but I didn't get too far. Also, windows doesn't
seem to have support for the 'hard-drive' UDF profile.
