Looking for a feature /programmer

Hi, hope this is the right place for this.

I produce very big panos in multires. Always flat panos and would need to things: A grid or display f x-y coordinates so that two people looking at the pano from different work stations 3 screen etc. could find the same point.
As an example, go to x 1258.36, y 589.032 to look at a feature on the pano.

A plan B would be to have a grid with x/y numbers that can be given to second party to find a specific point.

Any ideas ?

Yes that is about it. I did get a reply from Ulamo and he is helping out.
I will also need some help later on an an other project. Thanks for the interest.
