The OpenID 2 spec says:
"OpenID Authentication uses only standard HTTP(S) requests and responses, so it does not require any special capabilities of the User- Agent or other client software."
So I guess it would be possible for web services to exploit it.
I think the problem at the moment is any site or service has to provide two methods. A traditional one and an OpenID authentication and this increases the implementation burden without much benefit.
If it was just a little more widely accepted (perhaps google and microsoft live) then I'd be tempted to do a site that required an OpenID.

Roger, its a tricky subject. For me the biggest drawback of OpenID is that it needs as a client a browser for authentication, so it cant be used to secure webservices (openid2.0 might have improvements). Nearly any identitiy system I came across can also work as an OpenID provider by the way, CAS,Shibboleth,Google all work fine.

Hi Everyone,
Does anyone have any experience with OpenID?
Would this be a useful and simple way to provide cohesion within our community if one of the bigger members (GBIF, TDWG, EoL etc) acted as an Open ID provider?
I know there were presentations on Shibboleth at TDWG 2007.

OpenID seems simpler but does no authorization I believe (it is just an ID solution). Could the two be integrated for those who need to share notions of authorization...
I'd be interested to hear people's thoughts on this.
Thanks,
Roger
