Actually I think linking to wikispecies and other select databases  
(such as species pages currently offered by GBIF national Nodes) is a  
great idea.   In fact,  it would be done if we had the technical  
capacity to actively refactor the data portal as it's on a feature  
request list.    I hope we will be able to add this as you suggest.

As to the purity of my motives,  I really don't know what that is all  
about.
