It is great until your charity gets acquihired by a big think tank/bigger charity/international aid group and most doctors/charity operators are not known for their talent at scaling software.
In this case, this NGO is not going to get acquihired. It's more likely that I'll get an email in 5 years from someone who I don't recognize asking me if I know anything about this program because my email has been attached to this thing they got gifted from a dead project, and have been using after all of the original people have moved on. :)
