Seems to be an encrypted version of VNC, as except encryption, seems to behave exactly the same incl. the VNC typical bugs, ie, the non recognition of foreign keyboards (mine are French).
As for VNC, that can be bypassed at 90% by setting one computer keyboard (remote or server) as US and the other one (server or remote, respectively) in the foreign keyboard setup (French for me). However numbers are not recognized, except with Fn-J, Fn-P (etc) exactly as VNC... amazing coincidence, no ?
If their fix this, they will have a superiority over the "OSXvnc/chicken_of_the_VNC" couple, which still does not recognize foreign keyboards (and for which one must do the above).
As for VNC, these 2 softwares are faster than Timbuktu (mine is 603 Enterprise; using 512K ADSL on one hand and T1-gigabit on the other).
However, a good point: the documentation and easy instructions are online (thanks ! finally !).
We wait for more... The Linux version might be cool too.
