Microsoft employees getting Mango (7720) starting today?

This is just an interesting little tid-bit but we just got word that Microsoft employees can now get their phones updated to "Mango" 7720 starting today.

We were curious as to how this would be done i.e. if it is a similar process to how devs can now upgrade via Zune Desktop or do they just go to some guy's office, line up with their phones and have it flashed?

Turns out, it's actually closer to the latter part! Employees can take their phone to the Device Lab on the Bellevue campus and have it flashed to the finalized, RTM version of "Mango". That's pretty cool. So any of our readers want to chime in if they've experienced this?
