Camera Resolution Viewport

[goggle]

Hello,

I would like to know if there's a way to connect a camera view to the time slider.
Imagine I have 8 frames of animation and each one is view from a different camera, so when I go to frame 2 my viewport automatically go to camera 2, etc...

And my other question is : is it possible to do this same thing whith a Render preset and the time slider !
For example on frame 2 i got a resolution of 320 240 and on frame 3 a resolution of 640 480 and when i move my time slider it swtich from a resolution to another in my viewport !

I need to see the result of my scene quickly in my viewport with the correct resolution and aspect ratio to centre it before rendering.

So I hope that my request is clear, if it's not the case, please let me know.
In fact I just want to try to find a way to the fact that's not possible to set key on Resolution and on the Film Aspect Ratio of camera.

Thanks in advance

Look into render globals settings and how to set them using a command.
Writing an expression with switch block should do the trick.

CODE
//Psuedo code
int $t=currentTime -q;

//find out which camera it'd be
int $camno=$t%8; //Assuming 8 cameras

//or make an array of camera names if the naming is arbitrary

switch ($camno)
{
    case 1: //set resolution
               //set active camera to cam1
               break;

    case 2://set resolution
               //set active camera to cam12
               break;
     .
     .
     . so on
     .
    default: //Set resolution
                //Set camera
                break;
}

Thank you for your answer amitc, unfortunatly I'm not a programmer and I'm definitively familiar with mel language and it's like chinese for me.
I have tried to search an existing script on highend but I have found nothing in this way...
