Seems to work okay
I've been running it a home between my computers in the house and a tiny hosted virtual server in a data centre for about a year or so. Works perfectly well when I want my machines at home to appear to be in a different geographic location, and for my phone or a mobile system away from the house, when I want to check something at home.
As it stands for a small user it's pretty perfect and no more or less complicated than SSH to set up. Obviously once you have a lot of systems it doesn't have all the bells and whistles of OpenVPN, but then for a lot of small simple use cases it's pretty good. It also appears to be quite a bit more efficient than OpenVPN, which may be an issue if you're stuck with rubbish ADSL connections...
Biting the hand that feeds IT
