Remote Control Apps

In the next couple of days I plan to post a few reviews about remote control apps for the iPhone. I will leave out Apple's own Remote because I assume that it is installed on almost every iPhone anyway. No doubt that it is a great app, but it is also limited to control iTunes or the Apple TV. The remote control apps I consider do more than that.
There are different categories of remote control apps:

From a technical point of view:

1) AJAX based (WebApps, can be saved as bookmark to springboard). EyeTV and the Mac OS remote control application "Remote buddy" make use of this technique.

2) Native

From a purpose point of view:

a) Media control remotes: show buttons for fast forward, play/pause, volume etc.

b) Like a) but extended to more programs such as PowerPoint or Keynote. Dedicated interfaces for different programs.

c) VNC like full desktop control: connect to the desktop via VNC, Apple Remote Server or a dedicated server and proprietary protocol. Show the desktop's screen (over WIFI and 3G), allow mouse and keyboard input.

Some of such apps will be reviewed in the next few days. Stay tuned!
