[sugar] XO identity shared via Browse

[Greg Smith]

Hi Tomeu and Browse engineers,

Talking with Martin L recently he mentioned that you have some ideas on 
how the XO can communicate its identity (e.g. serial # and maybe user 
name) with a web server. We're mostly thinking of the school server as 
the server side but a more generic solution may be acceptable.

The main idea is to eliminate the need for students to ever type in a 
user name and password. e.g. they should be able to just hit the Backup 
and Restore URL and see their files without having to login or find 
their serial number in a list.

That's one example. I would also like any Web server to be able to 
extract the XO identity and use it in CGI (e.g. PHP) for processing.

It should also be encrypted so that the XO cannot be spoofed. e.g. only 
the XO which backed up and can see or restore its own files (possibly 
with an admin override).

I put a stub of a requirement for it on our roadmap here:

Do you have any ideas or designs for how we can achieve that?

Comments and questions welcome.

Thanks,

Greg S
