CTR, I agree with Sans assessment of the situation.
As far as finances, both the helo divisions of Lockheed and Boeing are tiny compared to the entire corporation and in different divisions from the larger fixed wing communities. The resources aren't shared across the entire enterprises. The JMR programs are also not entirely gov funded, there's very significant vendor investment and I would be surprised if being put for sale and bought didn't hamstring internal funding on the Sikorsky side.
I'm also glad to not be on the legal team that developed what I can only assume is 30,000 lb of legal papers firewalling the various Lockheed, Boeing, and Sikorsky interests into their proper buckets. :-)
