This "call home" is a HUGE advantage to Google because it allows G to collect a HUGE amount of user data

But what % of people install a toolbar, leave alone with advanced features? The lack of it can easily be compensated by other initiatives such as "Search History", "Google Accelerator". They are already a domain registrar which will help them in establishing affiliation. They may even become a low cost web hosting provider too, giving them a lot of data.

I'd consider who else the site links to, and who those sites link to

Interesting suggestion. But aren't you doing that anyway if there is a TBPR or not?
