Oh ... your dealing with users !
Is electrify device on open an option :-) ?
If not I would think twice about mounting a filesystem.
Disk file systems are often really touchy when you remove their
device. Often the reaction is to panic and halt the kernel.
( I have not looked at the linux fs code in a while so I might
be totally wrong here)
Take a look at mtools - it may do what you want without mounting
