I ordered a Deneb from AmigaKit yesterday, so I now feel entitled to my two cents worth of commentary. ;-)
Regarding Installer: The Installer executable is freely distributable pursuant to the terms in Installer.license and Germany's current export laws. (Has any incarnation of Amiga ever revoked that license?) Apart from storage limitations (Installer is huge!), it seems reasonable to include it with any installation that requires it. That's the most user-friendly approach, obviously.
Regarding MUI: C'est la vie. MUI is a near de facto standard with the unfortunate property of having an acronym that's the same as one used by Microsoft, although I gather SASG used it first. Hopefully, the Deneb documentation directs the end user to
http://www.sasg.com/mui or another appropriate location. I don't have MUI installed at the moment, but I suppose now's the time to get it done.
I once commented on the total cost of ownership of an Amiga system, including registration charges for the most commonly used system and user applications. It's a bit ludicrous. ;-)
I'm looking forward to receiving my Deneb. (I also joked about choosing a new nVidia display adapter over a Deneb. I guess I needed both of them.) It's replacing my Kickflash, which unfortunatley, doesn't support the MAPROM feature on the Blizzard 1260.
