Also, see the wireless stuff Katie did in the same article. Again - wow

Agreed!

You don't really need BeCu though. The primary advantage to using BeCu is the ability to easily solder it, which will not be required if you build a connector / cable assembly with spring pins similar to the one jebem and Dave Frederickson built. You can use any reasonably thin, springy metal.

Refer to the thread he linked, or to mine here. The spring pins and connectors required are explained there.
