Passport vs. Plan 9
netphilter writes "LinuxWorld is carrying an article about how Apache and Plan 9 are going to defeat Microsoft's Passport. I hate Passport's integration with XP (although that might be because I hate XP). An Open Source single-sign on would be a real blessing. Will we ever get a good single sign-on solution?"
Having 3 plans instead of one defeats the whole purpose of SINGLE sign on.
What we should have, as with any other Internet succesfull strategy is a single standard and competing implementations. That way we are insured to have compatibility and the added benefit of market competition.
