Well - clearly I've determined that there must be something with my office network.

At home, on my local wifi network, using my computername.local/dav I was able to sync my iPhone and sneakypeak perfectly. Worked like a charm.

Very happy about that, but crazy frustrated that I'm now going to have to try and track down what about my local network is the roadblock. That will be a challenge.
