Sent a note to VT editors, but as a FYI to users... It appears that Monkey Business Labs has become part of Magnetism Studios, and with a little digging it is possible to find it on their site (thanks to google). Here is their page on it:
http://magnetismstudios.com/MonkeyBusinessLabs/PackageTracker

Click Support, scroll down to FAQ, and you'll see comments about version 3, and the following:
"Why hasn't Package Tracker been updated? Package Tracker proved to be a difficult widget to develop and maintain. Future versions of Package Tracker will be developed by a pursued separate company."

So it sounds like SOMEONE is supposedly developing version 3, but its not clear who or when it might appear... Let's hope this handy widget hasn't died!
