[web2py] Getting started with appliances for web2py on GAE

[Niklas Rosencrantz]

Hi my web2py deployment is on app engine. I'm trying to add 
plug-ins/appliances using the admin area but all I get is an error message:
"unable to install application <APP_NAME>"
when trying to upload the package at 
https://my-app-deployment.appspot.com/admin/default/site
Am I uploading in the wrong place? It says the app I'm trying to upload is 
GAE compatible. Are all plug-ins / appliances GAE compatible?
Thank you
Niklas
