I like Opensource, I have been both Community Admin and Project Manager for several years in a community based CMS solution. I know a bit about how the development goes and what it takes. And the utter lack of cash or any money based rewards.
So I try to use free solutions, created in the same spirit of OpenSource, wherever I can. (No I do not fancy Linux...;-) )
OpenVPN was one of those. No more.
Hamachi was another, No more.
I will however admit that LogMeINHamachi is not expensive (29$ per year would suffice), but it is also a matter of principle for me.
Any tips?
