The official SAIFE Management C++ SDK by SAIFE calls the SAIFE Management API which provides access to SAIFE's security IP-based platform. This enables an application to generate its own keypair, establish itself on the Continuum, and securely communicate with peers. The current version is 2.0.1.
OpenID holds much promise as a means of supporting a single digital identity that can be used across the Internet. Currently there are several types of OpenID identity providers out there, and several of the major players on the web, including AOL, Microsoft, Google, and Yahoo!, have committed to become OpenID providers as well. While there is some concern about the 'Balkanization' of OpenID by these service providers (essentially the concern is over the fact that service providers will only provide OpenIDs and subsequently they will not become consumers of OpenIDs from other providers), the positive side of this adoption is that hundreds of millions of existing user accounts can now be used as OpenIDs.
