Question about controlling clients through server computer via FSUIPC and WideFS

I recently bought the fantastic BU0836A Ultra precision joystick controller from Leo Bodnar. It's connected to the server computer to control a few different functions in my pit.
However I also need to separately control some functions on my Clients:
1. Capt PFD/ND (PMRJ)
2. FO PFD/ND (PMRJ)
Today I use slaughtered keyboards to control different modes i the ND display like VOR, NDB etc. Due to instability of theese slughtered keyboards I need to use something else to interface.

Is it possible to do this through the server computer or do I need some separate interfacing device for each client? If so what would you suggest. Are there any, not too expensive keyboard emulators out there I can use?
