Sync MobileMe with automator

Okay, I'm having a problem, and hope you guys can help me with it.

Every time mobileme syncs--- it devours my bandwidth. I can't use Netflix, even checking my email or playing browser-based games slooooows down. It's fine if I'm working on offline stuff, but MobileMe is devour my bandwidth, and it's seriously making it difficult to use the computer. I've had to temporarily disable it. (I have a 6 meg connection... it shouldn't be doing this)

Is it possible to use Automator to set up MobileMe to sync at night, when I'm not using the computer? I can manually sync when I need to sync up contacts and calendars and such, but when all I do is change the SORT ORDER of a folder full of files, and I can't use the internet... that's annoying. I don't have this problem with Dropbox, I've never even noticed it syncing.

I sure hope iCloud is more efficient.
