I have deployed a couple of options that DO make use of extra bandwidth. One is radware. Another is a software upgrade to Watchguard Fireboxes. Another is some Cisco commands in a router with two Ethernet boards. But it only works with multiple users. AS a single user one cannot have two connections at once. Which would be DSL and Cable. This Only works if more people are on the LAN, that way you can cheaply increase the bandwidth based on predetermined factors such as user priorities or traffic levels. But you don't have to get fancy - You can simply route high bandwidth users out one pipe and everyone else out another just by changing a routing table for instance to alleviate congestion.
