I don't doubt that they're working towards making it technically feasible - thing is, Delta's intention to make JFK a full-fledged hub is certainly worrying CO and I'd bet the farm that CO is re-examining many of its current and planned cooperative activities with the Widget. It'd make good sense, IMHO, to disallow reciprocal upgrades between the airlines in order to protect the frequent-flyer customer base from poaching, much as AA/BA have mutually disallowed USA-London mileage accrual and redemption to protect their respective premium traffic bases.
