I was looking around the downloads today and notice this app:

DT-Talkie v2.1

http://maemo.org/downloads/product/OS2008/dttalkie/

If I read the description right, it sounds like you can communicate to other N8x0 with having a network connection. Does anyone have two N8x0 to try this out? And if it does work, what's the range on this?

Thanks.
