Use vmware fusion or parallels with a win7 image, run sop in unity mode. I install all the OS images on an external so no wasting of internal hd space.
And yeah, I have an X port running and made an idiot proof installer.dmg...Still pre-alpha and ages until I release due to being too busy at work.

There is a few russian builds out doing basically the same thing, though having had a look them it seems they have the same problems than my own port compile. Google Sopcast CXEx port
There is always the winebottler method, google sopcast mac.
