Well, one is in luck regarding inspiration for cyber-democracy. With the Machine Age expansion, Stellaris has some interesting forms of advanced government for such things.
One will, for the time being, forego explaining the Synthetization versions of governments, since one would presume that the players collectively are not in favor of going the Necrontyr route of uploading into fully synthetic bodies.
However, in Stellaris, there are Cybernetic advanced authority types. It depends upon the authority type being democratic, oligarchic, dicatorial, or imperial. There is also a further subdivision of whether it shall be individualist or collectivist.
If one is only interested in the democratic authority type, then the Cybernetic advanced democratic authority types are Democratic Concurrency and Democratic Interlink.
Democratic Concurrency is the Cybernetic individualist democratic authority type. In its own words:
"Highly advanced neurosecurity protocols allow citizens to vote on policy decisions in real-time directly."
Democratic Interlink is the Cybernetic collectivist democratic authority type. Its description is:
"Consciousness interfaces allow real-time sharing of sensory data, emotional responses, and thought patterns between full cyborgs. As a safeguard against the sensitivity of intense extra-body responses, emotional firewalls filter out unwanted responses to shared emotive data packets."
Real-time e-democracy/digital democracy, in other words, even with the option to share sensory data, emotions, and thoughts in real-time, complete with firewalls.
