It has been published already on many metaverse related blogs, but let me quote it once again

At about 11:00 AM, Linden, Ruth arrived on an OpenSim server, quite quietly. and to her surprise. We had been testing some code, and I’d asked Layla Linden to try to log on again, to see how the bug looked on the client side. But.. the latest fix, put on moments earlier, was, in fact, the last one we needed. I logged in as well, and several other folks from Linden lab joined us. Here we have Me, Layla Linden and Tess Linden.

What’s to unusual about logging into OpenSim? Nothing. But.. this wasn’t a normal login. All three Avatars had been logged on via the Agent Domain in the Linden Lab Aditi test grid.

Read the full story here. To describe it in very very simple words: They managed to login on the “normal” (test) Grid of Linden Lab and then “teleported” (it wasn’t an real teleport, but that will follow soon) to an OpenSim.

It has been possbile before to login to a OpenSim with the standard viewer, but not to move from the maingrid to an OpenSim.

But as pointed out by Zha:

Just to clarify a few points after talking to a number of people. This is very preliminary testing, and very much a “Oh, ok, so we can make this work, now we need to solve these three or four problems.”

Well, anyway - nice to see that things are making progress. Congratulations! (via eightbar)
