The FixMyLag stuff works by trying to (from memory) make TCP connections a little bit more efficient.
Unfortunately SC2 is entirely UDP based (can't really get much more "efficient" than UDP) so the tunneling services won't do anything unfortunately.
That's strange, because like I said, it has helped me alot for the past 1.5 years. Only lately it hasnt, and I am sure SC2 is TCP based but UDP for ingame voice.
