Because of the absence of good, solid business and accounting applications for Mac OS X, we have purchased a ridiculously inexpensive used Windows machine for under $120, cleaned out the hard drive, and our accountant will install their favorite Win biz app. This will be the only use of this machine, save for running a few small apps or opening stuff we used to use VPC for. We will connect this to our AirPort hub via the Ethernet port, and use the free Microsoft Remote Desktop Client on Mac OS X to open the Windows machine directly on our Mac desktops. Speed, stability and because the Win machine is not directly connected to the net and resides behind the Mac Firewall, we do not anticipate much in the way of internet viruses. Plus, our accountant and bookkeeper get to use their favorite application, which they already know the insides and outs on, we get a very inexpensive and feature-packed application that will do pretty much anything, it will cost about the same as an upgrade to MYOB (not counting no more VPC upgrades, which means we will actually save money), there's NO internet verification nonsense to stumble over, and we get to run it all on our Mac's monitors across the network (albeit small as it is).
