I am not sure what you mean by 'routed to one of your external ip
addresses'.
so, you are at a third site, and want a tunnel to both companies networks?
btw, I know those are just example addresses, but 11.x.x.x is not a
reserved network instead, that should be 10.1.0.xxx or something.

assuming its a routing that makes logical sense, it should be easy to
implement with OpenVPN. you'd need a firewall running openvpn at each
of those companies then your end could inititate the connections to each
of them. I'm not sure why you'd have to use two internet addresses at
your end, rather, you'd just have an net like 10.2.0.xxx and the VPN
tunnels would route between those networks. I'm assuming company 1 and
company 2 don't want any direct routing between them, so you'd have to
make sure you're not providing that route (eg, 10.0.0.xxx should not
have a route to 10.1.0.xxx or visa versa)
as far as 'better'? better is what you or the people who will be
administrating this is most familar with. often, easiest is to use VPN
appliance routers, like watchguards, or netscreens as the firewalls at
all these sites.
