Ink-Based Wiki: Should I Go Smart Client?

I am working on “Weka Wiki”: an ink-based Wiki (”Weka” being the Hawaiian word for “squid ink”). All pages will be rendered on any machine (as bitmaps on mundane machines), but the only way to edit ink-based pages will be with a Tablet PC. My question for the inkernet: when it comes to editing, is it important to stay within the browser, or is a smart client acceptable? Essentially, there's a lot more flexibility in terms of interface and editing in a smart client. Thoughts?

P.S. No one's even mentioned the initial release of Pynk, the ink-based Python IDE? Given the interest in Python in the community, I thought it would cause a little bit of a stir...
