I work in China for around half the year, and all Google-hosted content is blocked by the great firewall. This means that using Kashflow is simply not possible while I'm there. I don't think (as far as I can tell) that there would be any great difficulty in hosting the sorts of libraries (jquery, etc.) that are currently sourced from Google's CDN on your own servers. It would make all the difference to anyone working in a Google unfriendly location such as myself.
