Moving map that shows online aircraft through XSB?

I fly with an online group and we use our own dedicated server for the flights. (We also fly on VATSIM too)

Almost all members use either FS9 / FSX and when it's their turn to control they get on pretty well using one of the existing packages on the PC, such as FSNav or FS Commander. 

Question is, is there an equivalent 'moving map' type system for Mac OS?

I'm using X Squawk Box to connect to our server which works fine, and in the visual world of X-Plane can see all the other pilots without difficulty. The problems arise when it is my turn to control, as I can't find a reliable way of gaining the picture and perspective to control effectively.
