I too am considering a move to using my Mac as my only machine. Unfortunately I need to support a number of remote users using RAdmin.
Would love to see at least a RAdmin client (Viewer) that would run in OS X without a virtual machine or Intel processor in the Mac.
Since iMac and MAC OS have been introduced on the Intel Platform there's a steady erosion on the Windows side, at least in my environment. It's so much better. I would love to see an OS X version of both, Radmin client and server to connect the Windows and Mac world.
