[sldev] [AWG] realXtend login process for distributed virtual worlds

[Jani Pirkola]

Hi Tess,

thanks for commenting!

I am joining the AWG meeting today with realXtend developers and so we have
a possibility to talk about all the things around here. The coming AWG
meeting was the reason I posted the realXtend login process for everyone to
look at before the meeting.

It is certainly a good process that LL started and we want to be part of
that as realXtend project.

> easily.  Adoption of this standard protocol eliminates the need for many

> How does your avatar stay "online" to your friends while you teleport
> between virtual worlds?
> 2. Can you still IM your friends in Second Life when you have teleported
> to an OpenSim region?
> 3. How does the client choose how to connect to a region/server that's
> not on the map of the virutal world they are currently logged into?
>
> Only the login portion of the Open Grid Protocol is currently detailed.
> We will soon start fleshing out the Presence and Teleport protocols, and
> welcome your involvement. If you could contribute your thoughts to the
> Open Grid Protocol, either through the AWG meetings or commenting on the
> open document, we can work together to ensure interoperability with the
> realXTend clients.
