Suppose I have an iMac and a Macbook Pro. My Macbook Pro is my primary workstation, and when I switch to the iMac I would like my environment to be exactly the same in order to facilitate switching between the two during the day.
I read somewhere that it's possible to make a Macbook Pro behave as a simple external disk and connect it to another device that can read it. This means it might be possible to connect the Macbook Pro to the iMac and let the iMac boot from the Macbook Pro's disk, effectively providing the same environment on both machines.
Is this sort of thing possible? Will the two devices operate well while trying to boot from the same startup disk?

Depending on your Macs you might use the FireWire/Thunderbolt target-disk mode.
Apple-KB:
The target-mode-Mac will act as an additional external harddrive. You may use that as a start volume though and consequently have the MacBook Pro environment with a bigger monitor and better sound assumed the target-mode-Mac is your MacBook Pro.
But the environments on the two internal drives still differ. Example: If you add a user in the above case you will add it to the MacBook Pro System and not to the iMac System.
The only way to have identical environments is to clone one to another.
