Would it be as simple to change the permissions on the particular drive, and then just let the users have at it?
eg. sudo chmod a+rw /dev/mmcblk0
To be safe, you would have to disallow mounting of filesystems on that drive (or any other drive with the same media) because someone could make a filesystem on that media, create a SUID program in that filesystem (through raw I/O), mount the filesystem, and then run the SUID program. If I recall, there is a flag you can set on mount that prevents running of SUID programs on the filesystem…. that would also suffice. ../Dave
