Checkpoint vs Cisco

I am in a network that supports clients that have either Checkpoint v4.0 or Cisco v3.6.2. Problem is that the users I support need either one or the other at any one time. I have heard that both VPN clients cannot be on the same workstation. We do not have the luxury of having two separate workstations to run either VPN client separately.
Question: Does anyone know of a way to make both of these VPN clients work on the same workstation.
