Love this but running this JavaScript SDK in IE is a bit tricky. Basically, if you would like your solution to support 50% of internet users you would be forced to run your HTML/JS solution in a SSL-enabled server. I hope they enable a non-SSL solution soon. Oh! and forget about IE7 or IE6 users.
I was in your same situation. Once I managed to find a way to work remotely now I'm able to organize my time more efficiently and find time for my side projects/ideas.
