curious about droplets and synergy

I’m soon to have 2 macs sitting next to eachother each with its own monitor and i’ll be sharing a keyboard and mouse through synergy.

I was thinking of making a script.

the script has two functions

  1. The interface will basically be a large droplet window that is 1 pixel thick running down the left (right) side of the screen. When files are dragged into it they will be transfered through a ssh tunnel to the clipboard of the computer to the left (right).

  2. When the mouse enters the same line of pixels on the other computer it will plop those files onto the dragging mouse cursor.

My question is…how feasible is this. I know that I can do this with a dropplet pretty easy…but i’m wondering if I can write it so this acts like you are working on one computer with two screens.
