Limit download speed of mods

So yea,
my net is rather crappy and i'm always happy when a developer adds a download speed limiter in their updater/download stuffies. Reason is my net dies completely and is unusable when a regular download is downloading. Like a map with 200MB of size. Blocks my net for good 5 minutes where i can't do internet stuffies.

So i would really welcome an option to limit the download speed to 150/400/800/1200/4000 kBit per second for example. (I'd need 400 XD)

Thanks
