OpenID Mobile Profile?

[Nat Sakimura]

There are two issues involved.

1) URL length etc. limitations
2) User interface

1) has impact on 2).

For instance, we want to avoid the users pressing buttons when redirecting.
And, in many cases, we do not have javascript.
This means we are left with GET and this URL length limitation becomes an
issue.

2) cannot be solved globally because it could very well be somewhat
dependent on
the carrier implementation and handset capability.
For most of the phones in Japan, we can get unique
id for each handset at http level fairly securely so we can depend on it to
avoid any typing (not even username etc.). This was one of the factor why
m-commerce got so popular in Japan.

In many other markets, e.g., the U.S., this is not granted. Thus, some other
means
are required. I know, WIl Tan of Maleysia is working something on iPhone in
this regard.
Essentially, it needs to be solved per carrier or per handset class
(e.g., mid-p enabled phones, etc.), I think.
