I don't really see a problem with actual *work* involved all that much.
Given that all the official bindings are designed to be really thin
wrappers and that 0MQ 2.0.x is in deep API/ABI freeze there is no
forseeable maintenance to be done for 2.0.x, no?

The actual process in use is IMO up to each maintainer; we can provide a
template if this would be useful but ultimately (and especially with
language communities), everyone has their own preferred distribution
system/versioning conventions/...

If maintainers do want to try to provide a "one-size-fits-all" binding then
yeah, we'd want to add version macros in zmq.h to allow for detection using
these as well. 

Ultimately though I think that a well-maintained binding
will just have to support two 0MQ versions (current stable/maint and
current development/master).
