thanks for your feedback.

There are tons of features I'd love to add to Remote Buddy's AJAX 
Remote. That includes adding the ability to zoom in. However, as Apple 
has decided to not allow any third party development other than 
through a - JavaScript event-wise - more or less crippled browser, an 
efficient implementation of this feature is not currently possible. 
Adding this would - apart from making compromises with the user 
interface also mean to submit complete, high res screenshots, which, 
given the iPhone's CPU power would hardly be usable as decoding of 
such big images will take a fair amount of time. You'd get a new frame 
probably every couple of seconds at best and not at the several 
frames / second rate the AJAX Remote currently offers. It's focus, for 
now, is on being a tool for presentations, not to try to replace 
traditional remote desktop software.

Regarding the mapping of the buttons, this, technically, is sure 
possible. It's just that I wouldn't know where all the text should be 
displayed seeing the screen's space is already completely covered with 
the buttons.

Best regards, 
Felix
