So I'm having success at producing a prototype using the x11 server available from http://www.zinger-soft.com/.

I'm able to to pause and play rhythmbox on my netbook using my iphone with ruby/gtk. It's fast and responsive.

This should be easily recreated on the n900. I am having a hard time getting a demo up on the n900 cause ruby doesn't share the same love that python does on the n900. And I don't wanna be forced to do it in python or a C language.

But for anyone that does.. The trick is to get the X11 server ($2USD) from http://www.zinger-soft.com.
Open up a terminal on the host machine and type:
export DISPLAY=xxx.xxx.xxx.xxx:0 (xxx being your target ip (address)

Now any program you run will be displayed on your iphone/itouch.

Design your gui with gtk, a geometry of 320x480, and use button entered events followed by a gdk::display warp_pointer off the button.
Using the entered (as opposed to the clicked event) allows the remote xserver on the iphone to use a singe click as opposed to a hard to register double click. The war pointer is used to allow the same button to be "entered" more than once in a row.

Hopefully this weekend I can get a demo up. But ruby with dbus and gtk2 is fighting me all the way.

Edit:: I forgot to mention that i use mobilehotspot (with Titan's kernel) to get a connection between the iphone an the n900.
Props to the authors of those projects. Links when I get more time.

So here's a demonstration:

Attached a tar of my source.
Uses the ruby packages from this thread:
