So DVCS is great but given I write code in lots of places. I would like to be able to use a single id and sync across various servers.

I use my work domain account at 1 place
customers domain account,
Work at home discconected from any LDAP or AD server.

I don't want to manage the users either. So it would be great if people could just login with their facebook, google, or other OpenID and I could sync using those. just like this site allows facebook or Google. Why not plastic also.
