I know this is anecdotal evidence, but my granddad took multivitamins faithfully for years. After my grandma passed from cancer, and due to not eating as much food with those vitamins, his body had a calcium build up to a state of calcium poisoning. This did a number on his kidneys. His kidneys did not recover. Instead of dialysis , he chose hospice. Multivitamins have the potential to give too much for the body to handle.
Yeah, that's a great point -- especially for older people, you have to tell doctors all supplements you take, because some can affect how fast your blood will clot. For instance, I believe garlic supplements reduce blood clotting, so an older person (especially) might have complications during a surgery.
+1 for tinc, I can login to my server and see the other three computers, it's nice for ssh-ing or tunnelling.
On tinc, I was only able to get a Windows Remote Desktop connection for about 45 seconds, then it loses the connection. I'm guessing OpenVPN might not have this issue. Tinc is way easier to configure than openvpn though. I recommend it :)
