While I do agree that it certainly helps when demand is higher than supply in terms of customer interest, this is certainly not the main reason for the Google Wave invite/nomination system. I just got my invite today, and having used it extensively for a few hours, I can tell you a few things for certain: It is quite buggy, and still feels QUITE sluggish. Thus, it is in their interest to open this up to "early adopters" before the main population since they are more willing to tolerate these bugs. Furthermore, from following some of their twitter posts/blog posts, it seems like they are still struggling with scaling the system itself, contributing in the slow down in approving invites/"nominations" (it took my nomination 4 days to get approved, I don't think they're doing it to frustrate me once I've been invited ;)
