Hi David,
These are some great questions. Let me try and address them one by
one:
1.) Currently, OpenSocial is just an API that allows developers to
build applications on compliant social networks. However, with the
recent release of version 0.8 we've added support for a REST-based
server-to-server API. While this doesn't exactly guarantee
information sharing, it certainly opens up the ability for people to
build apps that work with data from multiple networks.
2.) What information is shared is up to each container. Most
containers will probably give users the ability to control which
applications can have access to their data.
3.) To prevent spoofing, OpenSocial supports the idea of signed
makeRequest calls. There's a bit more information here:
http://code.google.com/p/opensocial-resources/wiki/OrkutValidatingSignedRequests
4.) Sorry to say that while fetching email addresses is supported by
the spec, most containers will probably not be sharing this field for
privacy/spam considerations
Does this give you enough information?
