Multiple Sites - Cross Linking, benefits

[Maples]

Hi,

I have multiple sites (15) that have all the same technical framework. But they all have lots of good content (500 words a page, 35 pages per site). As they are all related by a keyphrases, i was going to link them all to each other at the bottom of the pages with each other.

Will google see some linking patterns with these sites that may impend their success?

That's a decent idea. I'd like to know this too.
