Sorry to respond/add to my own post, but there is another possibility that I forgot to mention: Create subinterfaces on the border router(s). Let's say that I'm connected to three upstreams, and communicate with the LAN via f0/0. Assume single border router. I create f0/0.1, f0/0.2, and f0/0.3, each in separate /30s. When the RouteScience box (presumed to operate using WCCP) receives a packet that it wishes to test, it forwards to the appropriate border router subint. The border router sets next-hop to a specific value that correlates to the ingress f0/0.x subint. Just don't round-robin packets from the same stream over different paths. (!) Unacceptable even for a quick test.
