Mashmobile have an interesting solution where essentially they run a small web server on the phone, which amongst other things can offer RSS feeds from your phone direct to other services. So your social network could be pulling photos straight off your phone without you having to do anything at all. Likewise videos, location - whatever data your phone can generate.

I'm sure most people want the ability to filter / edit before publishing, but it's definitely an interesting way of easing friction out of the publication process.
The other huge advantage of running a web server on the phone is that you can offer a way to manage the phone from a PC. This could have endless uses, from making it easier for you and me to set up the phone the way we want it, through to operator and enterprise management facilities. It also helps with inclusiveness (as discussed at Senior Market Mobile this week), because you'd be able to set up accessibility options on your phone from an already accessible PC.
