If a recruiter is looking at your portfolio, and wants to know your worthiness without contacting you, this will provide a way to see your skills and contact your manager for that project.
I created a plug in using JQuery which let's people create a skills cloud and associate it with projects by just specifying the skills set per project in the project description. The plugin handles on click highlighting of skills and de highlighting.
I have mocked stuff up for the data about project managers as I couldn't really get around to getting data from Linked In. But that can be done.
