Easy links from trusted sources

Ok, somebody pinch me or maybe I'm way behind and everybody (including the search engines) knows and has optimized using this technique.

What if you link to a highly trusted source that pulls in data dynamically. For example ...

http://encarta.msn.com/encnet/refpages/search.aspx?q=widgets

Google would go spider this dynamic page and add it to the index. So, why would you spend your link juice on something like that you might ask?

Do you see the "Windows Live Search Results" section in the middle column? What if one of those was your site? You just got a link from a very highly trusted domain (msn.com) and theoretically traded links with Microsoft.

So, has anybody used this method (not specifically this exact example) before? Does it work??

Some reasons I can see it not working is that maybe Google would disregard a page with only one incoming link. Maybe Google knows not to "count" those links for this exact reason.

Better yet, don't trade links, just have it spidered by way of Digg or other user contributed ("Web 2.0") means.
