Arduino analog input to MaxMSP 4.3?

Hi there,

I need to run some analog sensors (pots) through Arduino to MaxMSP 4.3. I don't own anything between that and Max 5, and in order to run Max 5 on the laptop used in the installation (not mine) I'd need to upgrade it to Tiger. Right now everything works fine and dandy, with the patch auto-starting, and I kind of hate to mess with it.

Is it possible to get Arduino analog information into Max 4.3?
