This rules is not suited for most OpenERP objects, but it works well for partners and products as these records are usually shared between companies, and all company-specific data (such as acounting data is set as per-company properties). A partner or product can thus be shared cleanly between companies. This was already possible before by just removing the company assigned to the partner, making it globally visible. bzr revid: odo@openerp.com-20110303155918-zjdgwnorsiex8y8u
