Man I dunno if anyone has really gone too far with PS3 modding recently, but some of the functions available now are AWESOME.
I just got PS3NETSRV working last night, so now I can keep my game downloads on my PC and stream the whole game across my LAN to the PS3.
It works flawlessly and saves the headache of FTPing them to the machine.
NTFS drives work now too, and so do PS2/PSX/PSP Isos!
