Ok, now that I've met with my client here's some additional information (and, of course, another question).

The client definitely does not have the physical space nor budget for supplying both Macs and PCs, and there are other applications/business reasons that require a Mac platform. Their current support guy is not supportive of the VirtualPC route so I'd like to get some information (PROs and CONs) of running a VFP app under VirtualPC. Additionally, where can I get info on what's required (operationally) to run VirtualPC (e.g., how do you start it up, can you have it start automatically, any impact of running VirtualPC while multitasking with other Mac OS apps, etc.). Basically, how does it flow as far as the user's experience?

Any info will help... they are actually wanting to have this app re-written in FileMaker Pro... Would like to save at lest one FP app from extinction!
