OK, here it is. I borrowed a wget function from a PowerShell repository, which is why it is written much better than the rest of the script. I'm definitely a scripting novice, so I encourage anyone to improve this or convert it to something that can be launched from inside xbmc.
What it does:
1. Downloads the html listing of jester's builds.
2. If a newer version is found (based on build number), the installer is downloaded. On the first run, it will always download the newest build.
3. The existing imdb scraper is preserved.
4. If xbmc is running, it gets closed.
5. New build installs silently.
6. Previous imdb scraper restored.
7. Build number written to ver.txt in xbmc directory.
8. XBMC starts in fullscreen.
How to run it:
1. Vista and XP only: Download Powershell 2 CTP3 (PowerShell 1.0 might work).
2. XP only: Download .NET 3.5 (2.0 might work)
3. Open a PowerShell prompt. In Vista/7, you'll need to run as an admin.
4. Run "set-executionpolicy remotesigned"
5. From here on, it can be run with powershell.exe <path>\update-xbmc.ps1 by an administrator.
Notes
1. Tested on XP, Vista and 7, x86 and x64. Running from a remote on Vista or 7 pretty much requires turning off UAC.
