I would like to get your opinion about a related topic.

What happens when different subdomains are aliased with unique domain names? e.g. sd1.domain.com may be aliased with sd1.com and sd2.domain.com may be aliased with sd2.com.

1. How Google treats cross-links from sd1.com and sd2.com?
2. Will the content at sd1.domain.com and sd1.com be treated as duplicate content?
