I have a Mac Mini that I'm using as a media center running Plex. I want to be able to watch the media stored there (a couple terabytes of AVIs, MP4s, etc...) from anywhere I am, on a laptop or hopefully even on my iPhone. Is there any hardware/software solution that will help with this? Using Back to my Mac or DynDNS I can mount my Mac Mini's drives remotely, but playing full-quality files over the internet isn't really possible, and it does't give me any options for the iPhone. I'm assuming that I'll need something that will transcode the files into a more web-friendly format in real time and make them accessible over then internet.

Options I've considered:
I've been looking at Slingbox, which seems to do a great job with this for live tv or a DVR, but I'm really just looking for a way to transcode/stream media from my computer. I don't have cable and don't need to literally control my TV.

I tried Orb for a while, because it seemed to include the features I was looking for, but it's Mac version was terrible and i wasn't able to get it to work even over my local network, let alone over the internet.

Also, the PogoPlug looked like an attractive option, but it seems like you have to manually convert your videos into a web-friendly h.264 format to make them streamable over the internet. I was hoping for a more on-demand option.

Is there anything I'm not thinking of?
