OpenID theory and Practice

So, now I have an openid, I have told my provider all about myself.
When I login to other sites, even for the first time (without having registered) I would expect the information provided to my OpenID provider to automatically be form-filled (at the very least)

PeopleAggregator doesn't do this (it isn't alone). I login and it asks me for my email, first name etc.
This shows me that what the theorists/visionaries saw as a future for URL identity and how it is actually being implemented is a long way apart.

If I have to tell my openid provider all about myself, and then have to do it all over again for each new site I got to, I can comfortable predict that OpenID will fail in its goals

Networking fatigue

I connected to Signon.com and in order to play around with OpenID and the Bandit Identity Card Selector.
It works great on linux, and.. , well... , not at all on windows.
In order to test the functionality, I have signed up with various OpenID enabled sites like:
Ziki
Plaxo

All these networking sites are starting to feel and look the same. How many different ways am I going to connect to people? Linkedin, Facebook, Plaxo?

My great Idea just burned....

I had an idea regarding starting a new technology business. It involves mobile data and retail point of sale.
According to Rod Drury anything involving these two will most likely fail. I'm gutted. I will have to consider my business model more carefully before lifting a finger.
