(Off topic) good way of networking?

[Andrew R. Brink]

Since you all are probably the smartest people i know of I'll ask this.

I want to network my computer and a friends computer together, he lives
all the way down the street......the problem is that i cant think of a
way to get cable over the street or under it.....we have a server that
we can put in the middle of us too.

Can you all think of anything?

Thanks
