Lacking modern features
UPDATE: THE CURRENT VERSION OF THIS APP WILL NOT ALLOW CONNECTIONS IF YOU HAVE THE MAC FIREWALL ENABLED ON THE TARGET MACHINE.
OLD REVIEW FOLLOWS:
This app works okay for my usage, which is mainly as a remote desktop application. I dont really use the remote administration or reporting features so I will not speak to those features.
The Good:
This app is nice in that you can locate other Macs, and either observe or control them or even run terminal commands. Connectivity to remote into other machines seems reliable. Theres a slider to adjust the image quality of the remote session based on your connection speed/quality. You can send power on, wake, sleep, power off commands without having to login to the machine. You can remote into another Lion machine without interrupting existing user sessions.
The Bad:
I have problems copying and pasting between the remote connection and the computer Im connecting from. The image quality is pretty dreadful even at the higher quality settings. There is no option to run your local machine as a native resolution display on the remote machine; that is to say everything is scaled or you need to scroll around your screen. It does not support Lions full-screen mode. If your computer is on a domain, the account that you remote in with must be an account on the client machine, but you can control any users actions.
