Conceptually there's no difference -- both get the job done. Since the
caricature of an emulator is that it is slow, it seems reasonable to at
least consider creating a native version of an application.

I never had a need for Win32-OS/2, Odin or WINE because I've never run
any Windows apps. I always found the concept mentally stimulating,
though, and paid a lot of attention because I've always been interested
in operating system design. (At IBM I wrote a 1401 Autocoder recompiler
in PL/I so the programs would run on the /360. The /360 had a 1401
hardware mode but you couldn't run both modes at the same time; this is
similar to having to reboot to run a Windows program "natively".)

Apologies that I won't be at any SCOUG meetings for a few more months.
I'll be missing some wonderful discussions.
