Guest accounts for tool access
We could have some or all tools that run in a “guest” account with limited privileges. This would allow people to try them without having to register. Maybe instead, they tell us their first name and current occupation (grad student, professor, etc.). Their sessions would time out quickly after the connection is lost, since there would be no way to get back to them. And there would be no access for ssh/sftp on this account.
