I'm the dev manager for Chamilo LMS and I happen to have developed the OpenID code for Dokeos in the past (which is the code that is still used today).
This would be a great opportunity for me to update the OpenID code to make sure it works better and more easily in 1.9.6 and future versions. I happen to have to update the Chamilo manual for admins for 1.9 this week-end, so I'll take the opportunity to add a section for OpenID in there too.
Just to be sure: the OpenID code acts as a "client" entity in Chamilo, it cannot act as a server for authentication (i.e. it requires a separate OpenID server).
I have no previous successful bid here but I have a solid reputation to protect, so I wouldn't be too worried about me not completing the project :-)
I'm also a Certified Linux Operator (Latinux certification, just a tad more complex than LPI101).
Even if you do select someone else, please make sure you/they drop me an e-mail to let me know about the changes so I can include them in Chamilo! (no charge for that, rather you'll be put in the Chamilo credits)
