Descalzo is indeed correct meistfx; he's been around long enough to have seen the numerous clarifications from admins, support staff, and the CEO of the company regarding SSH. It is not available for free hosting, no exceptions.
The default message you're receiving is because of SSH being blocked; the message doesn't state that we would be able to enable it, as that message is the default. We won't enable SSH for a free hosting account due to the level of damage that could be caused by a rogue user, or the amount of abuse possible.
Even if we could enable it however, the RED5 Media Server would not be able to be installed - software installation requires either a VPS or a dedicated server at a minimum, even on x10premium.
That said, there are freely available PHP/MySQL based chatroom scripts that will work, as long as you ensure they don't utilize a php document that never exits.
Edit: Should also mention that most of us in this section are volunteers as well, however that doesn't mean we're incorrect as most of us do have a way to reach admins for clarifications.
