Volo View is a for fee viewer that attempted to be the universal viewer for Autodesk products. It allows for viewing, markup, and measurement of the DWG and DWF formats.

or +-->VoloView.exe
DWF---+
Volo View makes a distinction between printing and plotting in that printing uses the system printer driver, same process used by Microsoft Word, Notepad, etc., but plotting uses a more advanced process - the same process used by AutoCAD. To accomplish this, Volo View comes with an add-on application that is a copy of AutoCAD OEM. It plots just like AutoCAD, because it is AutoCAD. This works for DWG only.

+-->VoloView.exe--->VPlt.exe--->paper
So far so good. The pictures gets a little more complicated when you consider that these various flavors of AutoCAD have "intelligent objects" -- data contained in DWG files that needs special code for them to be viewed properly. In products like Architectural Desktop, these would be things like doors, walls, windows, etc. To properly handle this type of data, what Autodesk calls "object enablers" have to be downloaded and installed by each Volo View users. They object enablers are free of charge.
DWG---+
+-->VoloView.exe+object enablers
Once a DWG is read in, it can be marked up using a variety of tools. The results can be saved to a DWF file or a redline markup file.
DWG---+
or +-->VoloView.exe+object enablers--->RML or DWF
DWF---+
If the RML file is used, it contains just the markup data and not the original data. This way the DWG and the RML file can be read into AutoCAD. This allows the original author of the DWG to see the user's suggested markup and make changes to the original data.

and +-->AutoCAD--->DWG

The process gets further complicated by Inventor, but is similar. Volo View attempts to apply this same process to IDW files.

DWF Composer goes the other direction. Rather than try to read DWG and IDW files and keep up with the changes to all of Autodesk products, it works with one format: DWF. All of the Autodesk products generate DWF.
DWF--->DWF Composer--->DWF
So this obviates the need for object enablers. DWF Composer can plot a DWF file to scale, so this obviates the need for VPlt.exe. For DWF Composer users who receive DWGs from their users, DWF Composer does come with a DWG viewer (again a copy of AutoCAD OEM juts like VPlt.exe) hat allows DWGs to be viewed, plotted, or a DWF generated.
DWG--->DWG Viewer--->DWF--->DWF Composer
In terms of markup, viewing and marking up a DWF results in a new DWF. Like a DWF generated by Volo View, this DWF contains the original data (unlike the RML file) plus the markup. This means the DWF can be sent to people who have the free Autodesk DWF Viewer. So whereas Volo View and DWF Composer are for fee, the DWF Viewer is for free.
DWF--->DWF Composer--->DWF--->DWF Viewer
AutoCAD 2005 has been updated so that it can read in a DWG plus the DWF and line them up so the DWF can be used as the markup data.

In a nutshell, I guess DWF Composer attempts to be simpler for users in that it concentrates on DWFs.
I know other newsgroup users will have tons to add.
