Two PacificPoker tables at the same time!?!

[RiverRider]

I'm using windows XP and I would like to know if it could be possible to open more than one version of the same poker software on a computer? Is there a program that I could use to create a "virtual session" on a computer that could allow me to open two PacificPoker software for example so I could play on more than one table. I know my IP address would probably be the same for each version but it looks like Pacific dont care about that.
