We've thought about this, but it wouldn't be easy right now to support two different "vdriver"'s simultaneously. We plan to add a "packages" feature to Executor that lets us have multiple modular instantiations of each package interface (video, events, sound, etc.). We may even release the source to these packages as dynamically loadable ELF modules under Linux, and as dynamically loadable ObjC objects under NEXTSTEP. mcculley> 2.

I'm sure we'll need to support that someday. Compared to the 68040, the PowerPC looks like a piece of cake to emulate (all 32-bit insns, load/store architecture, aligned memory accesses). mcculley> Will I be able to get a version of Executor that runs on mcculley> the Alpha? If the market looks promising. We actually had Executor running on the Alpha once, back when DEC loaned us one for a while. mcculley> If so, will it benefit when the emulated hardware and mcculley> the emulated hardware are identical?

This is what we do on 680x0 NeXT's running 680x0 Mac binaries. -Mat
