Khoros as SSO Source

I've found lots of documentation on using Khoros as an SSO client but I'm wondering if it's possible to use as the SSO source.

We don't use Khoros as an SSO client all details are stored directly in it's database but we'd like to add a 3rd party chat room software on to our community and set it up as the SSO client which talks to Khoros.

Does anybody know if this is possible?

Thanks
