I love the idea of linking our computers via DropBox. However, the download/upload process used in OLLY can be troublesome if more than one user is working on something (let's say, "Routines"). The manual suggests making sure only one person uploads to DropBox at a time. That's confusing for me. I don't want our whole school year to be erased because one of the kids uploads a routine at the wrong time.
This can be improved by using the same syncing method YNAB uses -- I think it is a database lock feature so that one user can't change something in the database while another person is syncing. Instead of an upload/download scenario, the updates are seamless.
But I'm VERY GRATEFUL that this tool uses DropBox.
