Ways to implement Janrain Engage (RPXNow) on Google App Engine?

What a some possible solutions to best implement Janrain Engage (RPX 开发者_StackOverflow社区Now) on Google App Engine?

For a complete solution including sessions, I recommend gae-sessions. The source includes a demo which shows how to integrate the sessions library with Janrain/RPX.

Disclaimer: I wrote gae-sessions, but for an informative comparison of it with alternatives, read this article.

According to this HOWTO, it seems to be pretty trivial.

This may article help you and you can combine this with the webapp2 which I believe already supports sessions.
