HP Blimp
Now this is what we need to reduce traffice congestion - in cubicles?
I like it, though. When you just need to send a Post-It ™ instead of e-mailing, phoning, yelling, passing it to your cubicle neighbor who's going for the coffee... In other words, this can only be useful for exchanging cryptographic keys. Which is bad, so it must be shut down! I expect that within months this page will either be gone, or the "project" will be abandoned. Just watch!
And then "Helio-Courier" will be replaced with "Whisper-silent Black VTOL Aircraft" in the skies of HP's cubicles.
