I got a test version Thursday and I have I played with it for a while on Friday. It works very well, it should be on target for late March. It is presently for Windows only but any upgrades will be available on the Tunze website as both firmware and software updates. I ran it on my IMac in VMWare using Vista, it immediately found the com port and everything ran easily. It did not allow me to hot swap the USB but I have never known Windows to allow that, though Mac's usually do without issue. Basically if you disconnect the USB you have to restart the program when you reconnect.
