Sorry, forgot to reply to the list.

Then it would be inefficient to route all packets through your vserver
first. A tunnel broker will presumably have better IP6 connectivity and be
reachable in fewer hops.

With private connections you mean connections between your servers at home
and your vserver? That would be the classic use case for a VPN, of course.
If you mean connections between your home servers and other hosts, then
routing through your vserver won't help, assuming you trust or distrust all
network operators equally. If you specifically distrust the ISP connecting
your home network then again tunneling everything over your
vserver will help.

Ask your ISP. If they don't want to help you, you won't have native IP6
unless you change your ISP. You don't need native IP6 to have your servers
reachable by IP6, even though native would be the preferred option.

When your vserver goes down, your servers at home will not be reachable
either. A tunnel to a network operator is likely a lot more reliable than
one to your vserver.

If the goal is to learn, then my considerations are not all that relevant.
Now, unfortunately I don't know enough about OpenVPN to be of any help
in answering the original question.
