I find myself intrigued lately with the possibility of using OpenID in B2B marketing campaigns and portals.

The idea is simple. Let your customers/partners use their existing Google, Yahoo!, Facebook, or AOL account to login to your website.

For a consumer website, this is a no-brainer. I would not be surprised if I could click on a Yahoo! banner ad and log into a sponsors website using my Yahoo! username.

But does this necessarily apply to a B2B website? I'm sure Marketers managing a complex sales process will continue to want to own the relationship end-to-end and collect as much information as possible upfront. But if a Marketer is willing to collect a minimum amount of information upfront and invest in cultivating the lead to incrementally collect more information over time, then this might work.

Less complex sales cycles might actually have quite a bit to gain by letting leads self-identify with an existing identity, given they're "in the hunt" and scanning 5+ competing site at one time. The site offering the path of least resistance is most likely to win.

RPX has a freemium service that supports OpenID (RPX is also an Oregon-bred company, so it must be good ). I'm going to experiment with the free version of this service and play with integrating it with i-Dialogue membership management (and by proxy, CRM Lead/Contact management). 

So what do you think? Would you support OpenID on your website? Why or why not?
