These are a few simulators for biological cells and processes.
I'm not sure this would be an effective strategy for hastening the pace of medical progress. My intuition is biased because I've spent the last fifteen years working with open-source software (Linux, Apache, etc). I recognize that competition and profit are also powerful forces driving the rate of innovation, and that these seem to work best when people aren't sharing information so readily. The software/internet world has seen lots of progress in the last ten or twenty years, and it seems that a mixed environment with both open-source and closed-source approaches has pushed things along well.
Software is difficult but biology is much more difficult. At least it looks that way from my software engineer's point of view. The depth of expertise required for meaningful contribution to medical knowledge will likely exclude most would-be contributors. I don't know what to do about that. Perhaps cell simulators and on-line information can make that expertise more accessible.
Participation by hobbyists has become a very big part of the astronomy community. Maybe there is a legitimate place for hobbyists in the field of medical research.
