So the issue ended up being related to WiFi, but not in the usual way..
Basically, I noticed that doing a DNS lookup to *any* external name server was taking roughly 5 seconds.. This is WAY too long, and XBMC gives up long before that..
Now, while my RPi was working perfectly well for pings/downloads/uploads etc, it seemed to be failing hard on DNS (UDP) stuff. My WiFi N USB adapter was basically dropping a LOT of packets whenever doing UDP lookups.. TCP stuff seemed to go through without issue. I haven't found the actual cause for this yet though. I have the RPi plugged in via ethernet while I do the texturecache.py run. Once its complete, Ill test with the RPi next to the router, over WiFi and see if that makes a difference.
The fact it only seemed to be dropping UDP stuff is what confuses me.
