uBoggle is a featured application!
[[http://uboggle.appspot.com|uBoggle]] is now appearing as the **featured application** on the [[http://appengine.google.com|Google AppEngine]] [[http://appgallery.appspot.com|Application Gallery]]. Thank you for your votes, and thanks to the appgallery editors!
And I have a screenshot for proof and posterity :)

The other day Michael Vrable was mentioning that he was dabbling with S3 and now I see that you are into Google’s App engine. I should get fundaes from both of you after the NSDI deadline :)
BTW, can’t you make the words be highlighted on the board as the user types in your uboggle app? Also, rather than start a new board for every user, you could create boards in “rounds” and have a leaderboard per round. Of all the boggle apps on the web, I find wordsplay.net the best for precisely this reason; the leaderboard gives the game an extra edge because of the sense of competition it creates :)
@Harsha: Actually we have a multiplayer version already, but it isn’t quite feature complete nor hasn’t seen enough testing yet so we haven’t publicized it much :) You can test it out at uboggle.appspot.com/multiplayer and let me know if it works for you. The highlight as you type is also very doable, I’ll add it to our feature-list. BTW the Boggle app on Facebook (Prolific) also has a good multiplayer version.
Great! The multiplayer version works for me, but I guess you need a higher page rank on Google to have multiple players there at the same time ;) Also, in the multiplayer version it would be useful to take the user’s nickname as input so that users don’t necessarily have to reveal their gmail IDs in the leaderboard :)
