Yes, my ultimate goal is to get it where people can easily run *both* the online version and offline version locally, with no need to host the online version.  It's a little tricky because of the problems that exist making request to third-party websites from a locally-running javascript program.  Really, this is the only secure way to do it.  SSL for the online portion is nice but still requires the user trust the person serving the site.  Running both portions locally, on my online and offline computers, is the only way I'd consider using this project for a significant offline transaction.

Anyway, this third-party request issue is partially solveable using CORS headers, and blockchain.info has recently, and very kindly, implemented CORS headers for this type of use case.  Anyway, I worked on it some more last night but ran into some very serious issues with AngularJS (the JS framework I used) HTTP client implementation and CORS compatibility, so I've ended up using Jquery to call blockchain for unspent outputs and to push the signed transaction (which works fine).  Anyway, I still want to do some more work before I announce it ready, and although I won't get to anything tonight, I should be able to finish up this weekend.
