Many of the big guns like 1800 Flowers, Diapers.com and others all have their sister sites in tabs at the top. Example: http://www.diapers.com/ with their 3 other properties. Since all properties link to one another on every page, it's really a wash, right? No real gain as engines know they are connected and it's the same link multiple times. No real problem either as it's natural for the user experience to have reciprocal links here between the brands. Any additional thoughts here?

We're rolling out quite a bit of pro video and hosting on a 3-party platform/player (likely BrightCove) that also allows us to have the URL reside on our domain. Here is a scenario for a particular video asset: A. It's on a product page that the video is relevant for. B. We have an entry on our blog with the video C. We have a separate section of our site "Video Library" that provides a centralized view of all videos. It's there too. D. We eventually give the video to other sites (bloggers, industry educational sites etc) for outreach and link-building. A through C on our domain are all for user experience as every page is very relevant, but are there any duplicate video issues here? We would likely only have the transcript on the product page (though we're open to suggestions). Any related feedback would be appreciated. We want to make this scalable and done properly from the beginning (will be rolling out 1000+ videos in 2010)
