Max number of users supported

Hi All,

I'm working on an application(using live Id authentication) that is pretty huge and I'm expecting almost 10 million users at the end of the year. Will Live Id authentication handle this many users?

I just looked at the unique ID string. It seems to be a 32 bit hex string. So there can be a maximum of 16^32 unique ids for an application. But, does it work this way?

Any insight on this matter will be very helpful.

Thanks,

Don
