I've been working on running OSX on a windows machine using VMWare; works really well! Simple procedure if you follow these steps:

Wouldn't recommend this setup for OSX applications that really need high performance graphics (using Quartz for example) but for using Opusmodus on a Windows machine this could be a nice option for those not able/wanting to invest in Apple hardware.
If you install rtpMIDI on the windows machine you'll also be able to run your audio software under Windows and connect Opusmodus using MIDI over a virtual network connection.
Big hug,
