No, as stated elsewhere, the <query> element in the jabber:iq:register namespace
does not allow a node attribute.

Yes.

Yes. Ideally, you could use adhoc-commands, but you'll need to convince client
developers to add support for it. You could always do both. If I understand you
correctly, you want to use iq:register to "SET" values on the various devices.
Instead of using a node attribute to do this, simply include a hidden field in
the x-data form that has that value. When a client submits the register back to
you, that hidden value should be included in the response. The other way around
this, would be to map the device-id's to "user" part of a JID: like this:

    vertical.ch1.scale at scope1.foo.org

This is not a good idea, since you would need to add support for this namespace
into all clients.

Same problem as (b).

This is essentially what adhoc commands is. You just need more widespread
support in clients.

Hope this clears some things up.
