Internships are generally for University students, but it's not a completely strict rule. I worked with a going-on-thirty intern, a graduate student with a wife and a kid! You'll definitely get some odd looks as a non-student, but there's nothing stopping you.

However, given that, I would shy away from the intern route. It is a step backwards in terms of respect and resumé building, and you have enough seniority to set your goals higher than an intern.

I would seek out a full-time job doing some interesting work. Amazon might be a good pick: they have a lot of interesting problems there, and they're looking for solid talent. I had an interview with them for an internship a while back, but ultimately declined the offer for a better position.

Also, don't reject anything that's non-webbish. I know the Web 2.0 / AJAX / Social shopping cart siren is appealing, but there are a lot of cool problems being solved in big established companies too.
