help w/drive encryption key on usb flash drive

[Daniel Mitton]

I am building a new system and what I want to do encrypt the internal 
HD partitions, but have the key/password on a USB flash drive.  Is 
this possible?  Do I need to boot from the flash drive or can I boot 
from the internal HD?  Do I need LiveCD?  Any good how-to resource I 
could get pointed at?  Can two systems use the same USB flash drive 
as the key/password?

Thanks in advance!
