I will definitely be donating. I met Stephen about a year and a half ago when this was just getting off the ground and he was (and still is) incredibly enthusiastic about going after such a challenging problem. When I mentioned that we had had relatively little success building such complex models he pointed me to the work modelling Mycoplasma genitalium [1]. The problem is not that we don't have the mathematical or computational tools or even the data to do it, it is that the social and practical aspects of organizing and integrating such a major engineering project are usually only available at companies with massive amounts of capital. Serious attempts to completely model complex systems are also usually beyond the scope of the least publishable unit. Hopefully open science will be able to bridge the gap. Good luck to the whole OW team!
I met John who worked on their (paid) iPhone app for the earlier prototype. There's one thing you can say it's that they are passionate about their project. The old prototype is here: (paid, is it OK to link this on HN?) https://itunes.apple.com/us/app/openworm-browser/id595581306...
