I thought some of the community might find this topic interesting, since many of the Myst games are on the wishlist..
"So, Cyan has decided to give make MystOnline available to the fans by releasing the source code for the servers, client and tools for MystOnline as an open source project. We will also host a data server with the data for MystOnline." [1]
"The 3D models and textures that were used to create Myst Online: Uru Live will not be part of the open source license." [2]

I love Mysts I though V, but not URU or URU Live. I played a bit of it when GameTap was hosting it, and it did absolutely nothing for me.

D'oh... No textures? That's like a Snickers without the peanuts.

i hate peanuts.

Even though the textures will not be open source, the rest of it may still enable users to bring back Uru Live.
