Maybe.  See below.

If you need a COM Runtime for Unix, Software AG provides one:

http://www1.softwareag.com/Corporate/products/entirex/downloads/download_exxdcom.asp

However, Mono doesn't provide *any* COM integration, on Windows or Unix,
so this wouldn't allow you to use Mono.

There is an alternate approach, though: Leave your COM code on Windows,
and write a .NET front-end which uses .NET COM Interop to use your COM
objects.  The front-end could be an XML Web Service or a
System.Runtime.Remoting server, both of which Mono can communicate with.

Thus you'd have:

	Mono/Linux --> [Network] --> .NET Web Service --> COM Component

This is likely the easiest approach, though its performance won't be
spectacular.
