There are volunteer programmers working on this. They are working on it in their free time while having day jobs, and having not attempted similar projects previously. While I think that offering financial incentive is a great idea, I don't think it addresses their stuck point (unless you could find a way to raise enough to hire someone experienced to solve the problem).
For an idea of what its like to take on a volunteer public good project, have a look at this post. I anticipate that they'll succeed in getting the alpha launched within the next month or two. If you know any programmers who are experienced with the Google Hangout interface and/or team leadership positions and want to point them at the group to help, that would likely speed things up.
We've had considerable interest and uptake on the Less Wrong Study Hall, especially with informal timed Pomodoro sessions for everyone to synchronize on. Working together with a number of other visible faces, and your own face visible to them, does seem effective. Keeping the social chat to the 5 off minutes prevents this from turning into just another chatroom.
We've been using this Tinychat room, and implementing everything Pomodoro-related with manual typing. Is there anyone out there who's interested in taking this to the next level with some custom code, possibly via the Google Hangouts API (Javascript), so we can have the following nice features?
This doesn't "seem" very complicated from a programming perspective (yes, we all know about things that don't seem complicated). The Google Hangouts API (possibly OpenMeetings) seems like it should provide almost all of the basics already. But unless some particular programmer steps up to do it, it won't get done. If interested, comment below or email shannon.friedman@positivevector.com, and please mention your relevant Javascript experience.
