Celery and RabbitMQ won't (I think) never be implemented in 
base_external_referentials (openobject-extension), I really want to 
avoid external dependencies. The connectors should be simple to install 
and configure (not the case actually).

base_external_referentials and base_sale_multichannels are actually 
sparsely pluggable, their 'inheritance' architecture doesn't allow much 
replacement of a piece a code by another. Work will be done on that too. 
So at end, a basic queue implementation could be replaced by any 
implementation which respect the same interface.

Maybe the experience will show that a queue based on PostgreSQL is 
sufficient for all installations and there will be no need for a more 
advanced queue implementation. Otherwise, ideally the installation of an 
additional openerp addon could replace the basic queue. (RabbitMQ 
supports thousands of messages per seconds, while Magento can take 
nearly 7 seconds to update 1 product, don't be too oversized :-)

In a general manner concerning the connectors, I started some months ago 
a analysis of the current state of the connectors and what could/should 
be done to improve the situation. It resulted in a document that you can 
find at link [1]. A second document [2] is a brief start of "what needs 
to be done" in first place.

We'll start to work on more detailed specifications in some time.

If you want to continue the discussion, I suggest to move on the 
magentoerpconnect list: magentoerpconnect-community@xxxxxxxxxxxxxxxxxxx

I cross-post my message on the magento list so everyone on the latter 
will be informed about that.

(by the way, I did an utterly rough PoC of Celery / RabbitMQ in OpenERP [3])
