I have two processes with over 1GB of virtual memory:

TruBlue Environment (classic) 1.13GB
kernel task  1.05GB

and the following, each with over 250MB of virtual memory

Adobe Reader    340.36 MB       
  WindowServer  335.61 MB       
Firefox         332.00 MB       
Safari          319.49 MB       
Excel           266.79 MB       
Mail            257.23 MB       

and 19 other processes using at least 100MB of virtual memory

Thanks for your input, Bruce
