I also think that most GCs would be flexible when it comes to a restricted set of voting rights within the TCCS until such a time as the TCCS is both economically and socially ready for a system along the lines of the Swiss model. Whilst I'm sure you would like to probe me on what exact political voting framework could be found to safeguard the TCCS I will request that I pass on this as I am no constitutional expert. However, that said, I am certain a political framework can be found that both safeguards the TCCS from GC political dominance but at the same time affords at least some voting rights (perhaps only at a very local level) to GCs living there.
Remember what exactly the mistakes of the past were:
1) TCs felt dominated by GCs and in particular felt very vulnerable due to their numerical inferiority on the island and the prospect of Enosis.
2) GCs felt frustrated by TCs secessionist stance and were continually wary of that secession taking effect with all its consequences.
Both communities mistrust of the other's true agenda fuelled the crisis to breaking point on more than one occasion.
Whilst TCs must not feel threatened by GCs and should not be swamped by them economically, at the same time GCs must not feel like the TCCS is a separate state in which they are not afforded the same rights. For some GCs (e.g. my father) the Annan Plan was enough simply because it made it clear that despite the restrictions along ethnic lines, the TCCS was under no circumstances to be considered a separate sovereign state. Had I voted perhaps even I would probably have been swayed enough by this one thing (+ my dad ) to vote yes. For the majority though, it seems that more is required.
I think you can have free movement and settlement in either state but the shall we call them invisable limits would protect and not encourage GC to attempt control of the TCCS. We need deterrants so that we do not repeat the mistakes of the past.
Invisible limits are ok as long as they remain so. The problem being that as soon as one GC is refused residence based on their ethnic background this will serve as a divisive force, something we don't want in a unified country.
