PS3 and Tversity not on LAN?

I have been running a TVersity server for a while. It runs on a high powered desktop sitting in my parent’s basement. They use it to stream to Xboxes/laptops in their home. I live 1500miles away and I access Tversity through the web. It all works great, no problem. What I would like to do is be able to somehow access the remote TVersity on my PS3. Is it possible to tell the PS3 to connect to a remote URL and stream from the same TVersity 1500 away? I know that I can use Hamachi and then set up a network bridge and plug the PS3 into my laptop, but I’d rather not do that if there is a simple solution direct from the PS3.

In a nut shell my question is can I access a TVersity server not on my local area network from a PS3?

I’d like to know this too, if so, how can you?
