So it looks like I'm leaning towards using this Pi for primarily a media center, and getting another later on to learn programming and to tinker with more extensively. So here is what I have working so far! I figured out how to set the name:
I also discovered, while perusing the settings menus on the Pi, that it is capable of performing as both uPnP device (hosting and recieving), and as an AIRPLAY receiver!!!! Needless to say, being the Apple fanboy that I am, this is exciting news. So I turned it on, fired it up and within a few mins I was streaming like a boss. I was hoping that I could use this as a work-around for Netflix, since they seem to hate Linux users and such, but to no avail. It seems that Netflix will only stream audio over airplay... No huge loss there since I have 4 other devices on that TV that do support Netflix, including the tv itself. Yes, I am a nerd... but if you are actually reading this blog then you are ok with that in the first place :p
Many other services streamed perfectly though including Crunchyroll and the Videos app, as well as the music app, which I have been enjoying thoroughy.
Here is a screenshot of the iPad streaming to it on what I'm pretty sure is crunchyroll:
And youtube from my iPhone:
Now, it's not perfect, but it works. For instance, on the iPad if I am streaming for more than 15 mins I have to keep it awake or the iPad goes to sleep (and subsequently it turns off the wifi) but I have the ever-so-useful jailbreak tweak "PreventSleep" to do that for me. I highly recommend this tweak if you do any amount of downloading or data transfer on your device.
I also hooked up my movie USB drive up to it and set it up as a DLNA server to stream that drive to my other devices. DLNA, for those not familiar with it, is a local streaming protocol that is pretty universally used. I could see it on my PS3, Xbox 360, iPad and iPhone (using 8player ~$5) but not the Roku, sadly.
That's pretty much it for now! I'll have a blog in a few days about the DLNA stuff, I forgot to take pics...
