The downside, of course, is that you now have a flow-based router in your network, which has been shown to Not Work Well under other specified conditions (worm outbreaks come immediately to mind).
I could be mistaken, but this is also a feature in mbgp, effectively loadsharing across two external paths. I presume the paths would have to be completely equal all the way down to the router-id and (probably) age-of-route ...
