MS-DOS BBS programs under 386 UNIXes

[Frank Ch. Eigler]

Does anyone have any experience with running MS-DOS BBS programs under
Unix running some DOS emulator?  Are there DOS emulators available for
386 Unix-es other than VP/ix which may be well suited to this?  Any
problems?

As well, how well are these DOS emulators suited to running multiple
copies of MS-DOS [programs] simultaneously.

We are particularly interested in Interactive's 386/ix and VP/ix.

We'd appreciate responses in E-Mail.
