I'm thinking of installing hamachi on my pi to access it from anywhere (no static ip), would this cause any problems with cpu usage do you think?
I have been thinking of that too (VPN's in general actually) and it is something I have been meaning to test but just have not got around to it yet. If you try it can you document it so I can have a play. I have deffinatly been thinking of including something like that in the future (with web ui links) somehow.
