Transfer windows for Googlezon

In the world of football the system of transfer windows ensures that selling and acquiring players can only take place in certain time periods of the year. I wonder if the same system should be applied to other businesses, specifically the lucrative niche of “promising-internet-start-up- certain-to-be-acquired-by-Google&co-any-minute”. A transfer window would at least give a start-up a few months to develop an idea before it is grabbed by Google & co. Om Malik noted a while ago that Google actively goes after start-ups in a very early phase to secure the talent before anyone else does. But at least they didn’t get YouTube cheap, or did they? Too soon to tell.
