K5 Router + USB keyboard Kindle input

Has anyone done this? I've just started searching a bit on this and found a few breadcrumbs, no clear answers.

I have an old Belkin router with a USB port running OpenWRT and am able to add other modules. I have a USB keyboard to plug in to the router. I would like to forward keyboard input from the router to the Kindle (Touch) over wifi.

The router and the Kindle can talk over ssh (both can be either client or server).

Whats the easiest or best way to forward the keystrokes to the Kindle? Ideally into ANY window where the on-screen window is up?

Thanks for any thoughts on this!
