Support for more than two PCs / cascading multiple DeskHop devices

[Fact0ryy]

Hello,

first of all, thank you for this project. DeskHop is a very clean and interesting hardware-based solution.

I have a question regarding scalability beyond two computers.

DeskHop appears to be designed to switch keyboard and mouse input between exactly two PCs.
In my current setup, I work with four laptops, each connected to different environments.

I already own a high-end TESmart KVM switch that can control four PCs across three monitors.
While this works well for video switching, I find the manual switching of USB devices via key combinations or buttons cumbersome. An automatic or position-based switching of keyboard and mouse input would be highly desirable.

Due to corporate restrictions, I am not allowed to install any software on any of the connected devices, so a purely hardware-based solution is required.

My questions are:
• Is it possible, or planned, to cascade or chain multiple DeskHop devices in order to control more than two PCs?
• Can multiple Raspberry Pi Pico or Zero devices be linked or coordinated to behave as a single multi-PC USB HID switch?
• Or is DeskHop intentionally limited to two PCs due to firmware or architectural constraints?

If cascading is not feasible, are there any known hardware-based or open-source approaches that provide a similar USB HID switching concept for three or more PCs?

Thank you for any clarification.

Best regards
