You are not forced to use long mode, you can still install and use 32
bit Windows or 32 bit Linux without problems.

A question for the assembler geeks. Currently DOSEMU other virtualizers
such as VMware, NTVDM or VirtualBox switch to V86-mode and back to
protected mode.

Is it possible to switch from long mode back to protected mode and from
protected mode to V86-mode? If so, such a feature is not implemented yet
into DOSEMU?

Well, VMware is not that good for 16 bit anyway. Depending on what
applications you want to run... VGA / VESA crashes often (the app does
not start, no freezing of running apps at all), bad SB16 implementation
etc...

VMware supports also shared folders (Works only if VMware tools are
installed? And there are no VMware tools for DOS.) and VMware has full
networking support (working in DOS but the available TSR's need afaik
all a lot of conventional memory).

You can try if DOSBox (full emulator, slow) works for you, you can mount
folders (recommend) or whole device letters on Windows. The content will
be visible in DOSBox and you may access those folders the same time on
Windows. But I don't remember how synchronized it was (after pasting a
new file into it you may need to restart until DOSBox sees, unsure...).
