Hi, Sasaki.
I'm predictably behind schedule with the tablet release of Klink, because I got side-tracked with some back-end infrastructure stuff that I intend to use with the new version. It will be ready soon, though, as much of the protocol support is written and tested at this point. When it is ready, I'll post a note here to the list with the exact instructions that you'll want to follow.
As an aside, Acer is in the process of rolling out Android 4.0 (Ice Cream Sandwich) updates to the A500, so with luck, you should soon be able to run the latest version of Android on your tablet.
