Serious question: do systems, which run KDE4 and are connected to a 10 Mbps 
wired network exist ?

Fast... if I see it correctly, this is a high-bandwith, but long latency 
connection. Are those machines all in the same subnet ?

Yes, distributed network file systems can even be faster than local ones.

I think we agree that there are enough corner cases, and that it is hard to 
find a really correct way.
But, can we still improve the logic a bit ?
