User Data: option where anyone w link is granted access

[d-callan]

trying to run a workshop for mbio, and our options to get everyone the same user dataset are:

1. have everyone upload and install the same dataset, which is time consuming and a waste of resources
2. collect a load of emails from people to share w them
3. make the dataset public

wed like to just give everyone a link and have anyone w access to the link have access to the dataset
