Thank you for posting to the Forums. That is an excellent question. You can set up numerous Guest Accounts with the Slingbox, to have the Slingbox on multiple accounts. However, there will be no way to determine which account is accessing the Slingbox at any given time. Below I have provided the article that will walk you through creating Guest Accounts.
If you have any other questions, comments or concerns, please feel free to reply back.
Hope this helps,
