You got a cellphone with bluetooth and still need to manually control slides when making a presentation?
Don't worry anymore, Amora (A mobile remote assistant) implements control of mouse and most of keyboard shortcuts (ESC, ENTER, SPACE, arrow keys, etc) making easy this task. Not only that, but you can take screenshots of the active window in your current graphic session (i.e. see thumbnails of PC windows in your cellphone screen).
Currently, the client is implemented in Python for S60 (Nokia cellphones) and the server is written in C programming language using Xlib and XTest to send events for X session and POSIX socket API for I/O.
