Highrise, the company-wide, web-based, shared address book with a few twists from 37signals, will allow login with OpenID. So much is reported by sneaky Chris Messina, and confirmed by DHH of 37s.
Chris concludes his post as follows.
I couldn’t be more excited about it. Finally, one login for all my Basecamps, Backpacks, Campfires, Tada Lists… and now, Highrise. This is exactly the way it’s supposed to work.
I hope he isn’t jumping the gun (again). I’d like to assume that all the 37s applications will allow login by OpenID, but I’m not sure that I should. Certainly Chris’ level of excitement is remarkable… and I thought I was going overboard on OpenID.
