Open source is the way to go. Any way Amiga items can get into more users is a good thing, especially if folks can tinker with a Mini-Mig style open source implementation of an Amiga tha can be rewoked into an Atari ST, or a Sharp X6800, etc or whatever.
There is also a great wow factor in having a sandwich box size Amiga connected to a Big LCD, without cumbersome VGA adapters, or spending 40 hours online looking for a HDTV that supports 15.75 klhz in RGB, and that can do pal for the occasional Pal game.
My dream is to have an AGA version in conjunction wuth a 3D VGA chipset. The VGA mode stuff would be available in WB via Picasso 96. For demos you couldcombine 3D VGA and AGA to and create some wild graphics effects.
For example have the VGA chipset scale the AGA screen.
Thinking out loud here...
