You can accomplish some of this with policy routing, and your "peon ubuntu" already has the software to do it. https://www.google.com/search?q=linux+policy+routing This is usually best if you know the traffic that your working with. If the connections are different speeds you could push your services to one connection, and your general usage to the other. Or similar with some traffic that's higher priority being pushed to the more stable connection. If you need more than that, you'll probably need a BGP setup.
