Hi David,
It appears that there is no easy way.
I got a Dell Axim a month or so ago - same PocketPC software as the iPaq. Cool devices.
Interestingly, the first thing that I wanted to do was to use the GDL web plugin ... figured a handheld was a great way to browse through objects away from the desk. But, that won't work on 'em the way Graphisoft has it programmed at the moment.
Apple does not have a version of QuickTime posted on their site for PocketPC. I found the following web page that talks about converting a VR to a Flash animation to enable viewing on PocketPC:

Note that current models run PocketPC 2003 which includes the Flash player, so the Flash download mentioned in the link shouldn't be necessary.
(While I can open a QT animation on my desktop version of Windows Media Player, I can't open one on the PocketPC version.)
PocketPC's have a resolution of 240 x 320 pixels. When viewing images in the image viewer (e.g., JPG), any size image can be viewed and rotated (landscape/portrait) It is shrunk to fit the screen - but can be zoomed to any size, and then panned by just dragging the stylus around the screen. (PocketPC-based telephones have fewer pixels on the screen - not sure what their resolution is.)
For Flash/web pages/media player, some of the pixels are used by menus and other stuff, so I'm not sure what the remaining max viewable pixel area is.
HTH,
Karl
