I found one AOE server implementation.

http://sourceforge.net/project/showfiles.php?group_id=130453&package_id=143790

It is not for production use. It can handle only a single file. The
configuration is not dynamically changeable.

The code of 659 lines works in user space. The block_target framework
can be very useful for it if we also provide a clean user-space
framework that we talked about in the past, though I'm not sure how
many people want it.


I found a kernel-space NBD server implementation, however, it's too
old (not for 2.6.X).

A user-space NBD server is the code of about 1000 lines. It seems that
the configuration is not dynamically changeable. So the block_target
framework can be very useful again.
