Sorry, I failed to mention that I need this to work on a Mac. I think that's why I avoided the GfW javascript/flash option. Also 1.2.x support would be nice, but probably unrealistic, and cross-platform support is more important (which I think where GNTP really shines). Also, it looks like the GfW js/flash option linked to on their website is not using GNTP which sort of defeats the purpose for me.
I was able to get some Ruby libraries to work locally, but that really doesn't solve my problem, since I need the browser to communicate with the client directly, not through the server (avoiding the issues of firewalls and static IP addresses).
Any Flash GNTP options with javascript hooks that you know of?
