Hmm.  It's fairly simple, and usually works just about perfectly, or not at all.

To use Distance (formerly called Acoustic Tape Measure):
1. Launch the activity on XO A.
2. Share the activity from the toolbar
3. Using XO B, join the shared instance from the mesh view
4. Click the big button on each machine (there's only one button)

That's it.  There should be a lot of whooshing, after which the enormous "0.00"
should change to be the current distance. There's only one screen, and there's
only one number field, and it tells you the distance.

What happened instead?  Do try in Update1-rc2.  So far, it's been working
perfectly fine for me, in either build*.

*: Due to mysterious telepathy/mesh bug #6061, Distance does not work in hostile
network environments like at 1CC.  This has not been a problem anywhere else, yet...
