I am reading now my rss feeds on kindle 2.
Networks:
Under Windows 7 every network has a label "home" "work" or "public" - Every label has its own firewall rules. Connection between PC and kindle is seen as network under Win 7.
I have granted access to kindle's IP only under realVNC settings.
kaffeine is a new solution I've never seen. I will try it now.
Tsinghoo has line by line refresh model. So your VNC is faster.
