Forms Server on NT + Web on Unix:Possible?

I read you can install/operate Dev/2K on the middle tier of a distributed three-tier architecture.

Does the Forms Server and the Web server need to be on the same machine and/or the same operation system?

Can I do the following?

Product                                Operating System
--------------------                   ---------------------
Forms Server                                NT
Web Application Server    3.0        Dec Alpha(Unix) using Netscape
Database Server         Oracle 7.3    Dec Alpha (Unix)
