I wouldn’t worry about any paths in the screen shots, they were directly read from my mt-daapd.conf file. (and this is just a VM i setup for testing WHS dev stuff)
Installer – MS WHS SDK shows an example of using WiX to create a .msi so i’ll take a look at that. If you do it right, you should be able to copy the .msi to \SERVERSoftwareAdd-ins and then the WHS Console Add-ins tab will pick the package up and let you install it directly from within the console.
I’d certainly be happy to host it with the rest of the firefly stuff, although i’ve never used SVN before…
