Success! I was able to successfully stand up an instance ( http://arduino-tweet1.appspot.com/of NeoCat's terrific Twitter proxy on Google AppEngine. If anyone is interested in setting up their own I can help with the process (and help you not repeat the many mistakes I made ;). BTW, the code, available here GitHub - NeoCat/ArduinoTweetLib-server: ArduinoTweetLib server for Google AppEngine , is distributed under GPLv2 (http://www.gnu.org/licenses/gpl-faq.html which means you can take, modify and use it according to the normal attribution provisions (and thanks to NeoCat!).Drew
I'm interested in cloning arduino-tweet.appspot.com. What tips do you have?
