Hi, Willem:
This looks really cool. It's going to take me a little time to get it
put together as I have some commitments the next couple days that will
take time. But, I wanted to acknowledge your email right away.
I will definitely follow through on this. This sounds like a really
useful tool. And, you're correct that I have a handful of devices handy!
<grin>
Best,
Janina
