i was thinking about an app that would need the user to sign something on the iPad. Is this possible (perhaps with a special kind of pen)?

Thanks in advance

Maybe the most important idea and the success factor of iPhone and iOS in general that you interact with the device using your bare fingers, no need to stylus or any thing.
I recommend you watch Steve Jobs keynote when he launched the iPhone for the first time.
I'm not an expert but I think you can implement your requirement using custom gestures.

I think it is possible as in Ipad 2 we can write on the notepad using our fingers. So I believe this can be achieved and as John mentioned, no need to stylus.

Hey you can do it by getting the touch event of finger and by getting the coordinates you can draw signature on the screen and you can also store them. Their is many other ways to do it. no need of any pen at all.

Apple has developed code sample for that - GLPaint(OpenGL ES based). You can find it at iOS developer center.
