Wireless Networks: Connecting buildings together

[KTorak]

I need a little help here. Whats the best way to connect 2 buildings around 600 ft apart? I currently have a Linksys BEFW11S4 wireless router.

Option A:
Figure out which antena port on my router to use and plug in a Directional Antena to the building.

Option B:
Setup a Linux box with router app (I'm sure I could find one) and use a desktop card..but remove the antena and connect a directional one.

Foreseeable problems with A:
I think I'd lose my local wireless if i removed an antena and shot the signal to another building.

Foreseeable problems with B:
Aquiring a linux box and the software to use.

General probelm:
Would I need a directional antena at the other building to shoot the signal back to my house so they can communicate?

Any help is appreciated.

1) Yagi Antenna
2) You don't have to unless you need to have the signal go across 10 miles of air.

The easiest way to test this is by building one from a pringles can:

Now, this all comes with a nice little warning about breaking FCC regulations, as seen here:

But if you're beyond that, then it's all good!

(P.S. Unless you want to retain your eyesight, I don't suggest staring down one of these tubes while in operation. The firing electrons and the 2.4GHz connection [which just so happens to be the resonance frequency of water {microwave}] can hurt a bit.)
