Hi Bill,
I've actually got a skeleton web interface working now, complete with ipod touch and iphone support. I'm working out all the kinks, but it's definitely coming. (It's still secure, too, everything is encrypted client side, the web app is all javascript). If you're curious, optimizing AES in Javascript was not fun
It likely won't be free, though. Since I have to maintain a server and such to make it happen, I want to make sure there's long term viability, so the web app will likely come with a monthly subscription (I'm thinking $0.50/mo, or $6/year). What do you think about that? Would you still use it?
