This post is just for mirroring a file that was found in this nuigroup post.
From the post:
I developed my first Android Applictation that sends TUIO data via Wifi to a receiver.
You can define your receiver easily by changing IP and Port.
It should work under Android 2.1.
It is in a beta stadium, a really good blob tracking is not implemented yet.
The file was linked via rapidshare and now the link and file is gone so I am mirroring it here.
The file is an apk, so just copy it to your phone. If I can get ahold of the source, I will update this post with it.
Here is a qrcode if you want to download it directly from your android phone:
