Is it possible to run two versions of Google Chrome?

How might I run 2 versions of google chrome so I can log into to 2 different google accounts.

More specifically I am looking to have separate icons in the dock for the 2 separate running applications.

How might I run duplicate and or copy versions of the same application. The following linked question on SuperUser by Mark works for a lot of applications but not for Google Chrome.

It appears the following works link.
