Yes. But it should speak to the client. Not to the grid. So the
client can fetch the data and then push it to the grid server.

Perhaps, yet there is another perspective. What constitutes the grid?
In most technologies that have included the now outdated semantic web
and the more recent Web 2.0, the grid is more distinct from the client.
Web 3.0 is much different from Web 2.0. To describe it in buzzwords,
the semantic web has been ejected and the clouds have rolled in. The
grid, in Web 3.0 terms, may include several web apps found on various
websites, and the client may only be just the web browser (no special
download like Lively does). In order for those web apps to talk to each
other without one person logging in to all the websites, we can use
OpenID. The web apps and opensim together are what used to be the grid.<br>
<br>
Even if the sims aren't quite Web 3.0 at this time, there are standards
being made for it.<br>
<br>
More can be read here:

And: <a class="moz-txt-link-freetext" href="http://www.axschema.org/">http://www.axschema.org/</a><br>
<br>
For example, RESTful calls from opensim can poll openid servers to
initiate an attribute exchange of avatar information. The user, also,
can look and change the avatar being referenced at the OpenID server,
like maybe with a URL: <a class="moz-txt-link-freetext" href="http://username.openid-example.com/avatar">http://username.openid-example.com/avatar</a>. The
OpenID most likely would not hold the actual data, but another web app
could provide the storage for the actual content. The reference of the
avatar at the OpenID server is just meta data, unless one wants to
propose a standard at <a class="moz-txt-link-freetext" href="http://www.axschema.org">http://www.axschema.org</a>.<br>
<br>
If OpenID was used in this way, then without even being in the 3D
client, one could buy clothes from one web app and transfer them over
to another web app that acts as the user's inventory. There is already
development to allow such a transfer with the current grid, but it
still is based on a login to the grid instead of OpenID.<br>
