I have Mainstone running as a USB storage device using 5MB of tmpfs /tmp/data as storage. 

I can loop mount an ext2 fs and read/write data on Mainstone as expected.

There are whinges if I use /home/data (jffs2) probably due to jffs2 compression or something - yaffs should be fine if thats the case. The problems are there when reading/writing to the loop mounted data as ext2 so its not a usb specific issue.

Plugging Mainstone into a linux laptop yields a new /dev/sda as expected. Mounting this in the usual way on the laptop does all the expected stuff.

This should be a convenient way to share data between loon#3 and windows boxes.
