ISeeWhatYouAreDoing is a useful tool for getting screenshots and executing commands over Tcp/Ip or Ftp. Because it has NO security the Tcp/Ip part shouldn't be used in public networks (Use a firewall! :)). It was designed for easily keeping an eye on what people in your home network are doing and (if necessary) turn f.e. your brother's computer off when he forgot. As said it is able to work on very bad connections. Bin/Bin.zip is the basic package with client and a gui server, Bin/Hidden_Server.zip contains the "serious" version with a useful config.txt, no gui (server should run in background) and uses mainly ftp to get its commands, although you can connect via Tcp/Ip and the client from the Bin/Bin.zip or Bin/Client_Only.zip package. The hidden server has an English readme! For further information about the usage of the program please look at Doc/ or at the readmes in Bin.zip (currently both German, sorry). I hope v0.3.0 will follow till 12/12.
