Which (surprise!) is the same thing as a properly configured linux box. :P Basically, you simply need to make sure you configure routing for=20 the "internet at large" correctly. This will generally involve some sort=20 of source-based routing and/or some custom dhclient scripts and/or=20 assigning proper metrics to your routes and telling the kernel how to use=20 those metrics when there are multiple routes to a single IP. We have two networks here at the house: the cable internet (9Mbps/1Mbps,=20 but those speeds can't be counted on, dynamic IP) and the DSL=20 (1.5Mbps/512Kbps, I think, block of static IPs). I've got two NICs so I'm= =20 on both of them. Virtually all traffic uses the cable connection (http=20 requests, bittorrent, etc.), but the DSL connection is available for=20 traffic (ssh, local mail server [on the same subnet], etc.).
