Hypothetically, yes. Realistically, no. There would be two ways of doing this. One would be directly tapping the server, which if we could do there would be no need for FLPs because we would just have the usernames and passwords all ready for us. On the other hand, the more viable option would be to send data to the Gaia website, checking if the login is accepted, and then sending the data back. But that is to much work.
