[webteam] XML files for public transports

[Alexander Jones]

I just want to chip in and comment that, currently, non-local
transports *suck hard*. The main reason being is that we don't have
roster item exchange yet, and this creates a lot of nasty issues that
eventually and inevitably bite people in the butt. If you haven't had
problems yet, you're lucky to have lasted this long. I'm back to using
WLM via Emesene when I need to.

In summary, I don't think we should be promoting the use of external transports.
