Sometime in the future it will ported to 2.6 along with the OpenSSI code 
that depends on it.

It would be good if both CI and OpenSSI became part of the main-line 
kernel, but there are no specific plans right now. CI would be an easier 
sell, because it has far less hooks into other kernel code. 
Nevertheless, I think it needs to have a reasonably sized user community 
before Linus would accept it.

No.

CI requires software that uses its features to truly be useful. By 
itself, it's just keeps track of cluster membership, albeit rather well. 
The only software I'm aware of that uses CI is OpenSSI.

I don't think any of us have looked at the AIS spec in any detail. It 
would be nice to have a common clustering API. The reason CI was 
spun-off from OpenSSI was to try to promote a common membership 
interface for all clustering software, but it's been difficult to 
attract other developers to build apps on it.

Hope this helps,
