OpenVPN seems to prefer the use of certificates, as well. I generally
just utilize static shared keys, but the certificate powers OpenVPN
supports are quite nice.

This is, essentially, true. Due to OpenVPN's design, a few individuals
of late have been working on changing this. There are now two separate
schemes available to allow OpenVPN to work with multiple clients all at
once. Really, neither is effective with many clients... more than ten
or twenty... but they both allow primary control over a single TCP or
UDP port. They both, I believe, require the use of multiple
configuration files and TUN/TAP devices.

Does it do that, or does it just bridge multiple VPN connections
together into a single bridged interface?

Point to point.

I'm not sure there have been any... however, OpenVPN is *so* tied in to
OpenSSL, it really, IMHO, is as secure as any other OpenSSL based
application out there. James seems to have designed it with security in
mind from the getgo.

If tinc scales well (and I don't know if it does or not), then I would
have to adjust the deciding factor to be how many hosts. If we're
talking less than twenty hosts, of which you're administrator over all,
OpenVPN would be the route to go. If we're dealing with more than
twenty hosts, tinc or some other VPN product would be the way to go.
OpenVPN is also developed for multiple platforms, including Windows, the
BSDs, and Linux. I really don't know about tinc. :-)
