Dear Diva,

I am realXtend project manager and we have just started to contribute code
to OpenSim project. One of our key sw components aim to this kind of
authentication and cross-grid functionality. We will make a release of all
of our sw components, including user authentication, at the end of this
month. These components will appear to OpenSim svn even before that.

Only drawback is that our approach is not (at least yet) SL-compatible. We
have also developed our own viewer based on SL Viewer, but with many
enhancements. You might want to check our web site, which was just opened
few hours ago: http://www.realxtend.org.
