I have seen that RPXNOW can be supported .But I don 't know how to getstarted with it.

And I have seen your post at http://www.boonex.com/unity/forums/topic/OpenID-Sample-Code-for-Dolphin.htm .You said that there is Openid support with new version. Could you tell me where do I get it?

no open ID support  sorry.  there is an RPX mod out now in the boonex market.
