I'm on the Windows Basic package which gives me 300MB of space - currently its almost full of pictures I took while in Australia (
www.murfituk.com/australia if you're interested).
It is a proper paid-for web hosting package, not the free space you usually get from your ISP.
If :8443 is a protocol for sharing data between computers I'm still not sure how it can be so fast. Its still using my ntl connection to get the data onto my computer.
