I'm mildly surprised you have in-application bandwidth limits instead of setting up clever firewall rules on your local box. (Latency in particular is a fun thing to add.)
I wanted a cross platform way to test slow connections with a single command line parameter. Whether it be Linux, FreeBSD, or OSX (maybe Windows (haven't tested :-P)), it is easy to setup.
iptables or putting nginx with rate limits in front of Fake S3 would be a more powerful approach, but also harder to get going.
