Adobe Reader: sync browsing in two instances

Could someone help me to get a script that allows browsing in two instances of Adobe Reader, so that the page numbers match?

At the left-hand side I’m viewing Left.pdf in full page view. At the right-hand side I’m viewing Right.pdf, also in page view, with the Comments bar enabled:

I don’t think Adobe Reader has a applescript dictionary, so this would at best be a PITA UI-scripting job.

I didn’t look into it specifically, but it’s probably pretty easy to script if you can use Preview instead of Adobe Reader.

Thanks, but I really need to use the Comments feature of the Acrobat Reader.
