There is an application that have been waiting on and really want to use, well, at least I think I do. Then the vendor told me it required a 64 bit Windows OS with at least 8 gb of RAM. I was expecting to run it on a Linux, Solaris or Mac server and just be able to access it from my MacBook in an X Window. So now Im wondering if I can put it in an XP64 virtual machine and put that on the Linux/Solaris/Mac server and access that from my MacBook while I travel. Is there a limit on the amount of RAM you can access through VM ware? One of our more savvy IT guys told me it was 4 gb. Does the virtualization software that runs under Solaris let you see more RAM? Should I buy a Dell Workstation notebook with 8 gb (ack!). Thanks for any suggestions or info.
