Our latest version is technically on Caa1, so there is no "our" version yet. Putting any other mod on Caa1, would require permission from kju, not us.
We have released our A2 version of the map on Bohemia forums but it will be mostly like the Caa1 map with nicer textures, grass, and more properly ported to A2. You can play with using that if you want.
I know the epoch guys at some point asked about using or supporting Sahrani.
We have no problem with that at all. They are also welcome to have a look at our A2 release.
Currently we are testing the Next version of DayZ Sahrani which WILL be on our A2 version of the map. Should be out in just a couple weeks (3-4 or so).
We are working on putting together some pbo packages for server hosts that they can use to place their buildings w/o bumping into ours.... and for movie making, and editing in general...
Of course, it will be only for my server and I will ask you the permission and share with you my findings Don't worry. I don't steal things exept for thos who are making money on free mod like origins devs
