lets say there are two AD forests which by coincidence happen to have same name, for example "foo.local". Is it possible to establish a trust relationship between such forests?

I really doubt it, but more to the point, I'd strongly recommend against it. Even if technically it works it's going to be so horrendously confusing to diagnose issues that I would never even entertain the idea.
