[Very sorry we missed the ttx last week.  We found out about
it too late; looks like fun and useful.]

We've opened for public use four major new features in Utah's Emulab
network testbed.  They are documented and ready for anyone's reasonable
research or educational use, or just take them for a test drive.

1. 900MHz Motes and 802.11 Stargates on robots: a truly mobile
wireless testbed, with experimenter-specified movements, simple path
planning by Emulab, a vision-based tracking system, live maps, and
webcams.  Control and monitoring are completely integrated into the
existing Emulab system, so a mobile experiment is very similar to a
typical Emulab experiment.  This first installation is small, but it
all works.

This is really three features: mote support (e-mote and Stargate-
hosted currently), Stargate support, and mobility.  We have a
few fixed motes, and will be adding lots more.

2,3. Secure environments for running malicious or risky code:
      A per-experiment switch-enforced firewall.
      A per-experiment Emulab, by providing Emulab-in-Emulab.
Plus, at no extra charge, color-coded security levels that
automatically set up different defense levels.

4. Windows XP is a supported test node OS, joining Linux and FreeBSD.
Most Emulab features work, including ssh keys and file service.  It's
got Remote Desktop if you need Windows look-and-feel; it's got Cygwin
if you prefer Unix.

Finally, let me remind you that we also have a non-mobile 802.11a/b/g
testbed available: 27 PCs scattered around our building, most with two
Atheros cards.  You can change the madwifi driver, the OS, everything.

Kudos to the whole Emulab team, but especially to Tim Stack, David
Johnson, Dan Flickinger, Leigh Stoller (robots); Mike Hibler, Leigh
Stoller (secure env); and Russ Fish, Kirk Webb (Windows).
