Good to hear about OpenMRS, you might have also know about the Open

Yes, I have watched several of the videos done on these projects, and somewhat familiar with the OpenNotes project. IMHO there's going to be a huge increase in FOSS projects for health IT & healthcare management as resources continue to be stretched. So it's great to see people supporting their development!
