the reason why it's not working is the same for why klipper is not 
working: clipboard is not a shared medium anymore, but the compositor 
grants applications to write to the clipboard and to read from the 
clipboard. Both is strictly tied to having (keyboard) focus.

For kdeconnect this means it's not possible to write to the clipboard 
nor to read from the clipboard as it doesn't have a gui which could gain 
focus (obviously having a gui would not really be a solution here).

The ideas I had was to have a kind of clipboard manager which is always 
informed when clipboard content changes and is also allowed to write 
clipboard. I had a draft protocol, but I never got it to work properly 
for the klipper case as it tried to sync into both directions. But for 
the kdeconnect case the approach could work. Basically what we need is a 
protocol which allows to always set the data source and to get data 
offers. This would probably make sense to have in wayland-protocols as 
it's a rather generic problem (e.g. also virtual machines need this 
feature).
