I'm surprised nobody has mentioned autofs
http://freshmeat.net/projects/autofs/
And here's a how-to for the faint-hearted:

Personally, I have autofs configured to identify the device by the
name/description it sends to the computer (the name you can see with dmesg,
like "USB Mass Storage"). It will automatically create a symlink to
whatever the device is and call them, i.e., /dev/usb0, /dev/psp,
/dev/camera, etc. Furthermore, I have it set to automatically mount said
device every time I try to access whatever directory it is to be mounted on.
It's a useful little tool so you don't have to deal with your usb devices
being mapped to /dev/sdr or w/e.
