Description of Problem:
Nautilus ,atleast, should be able to download
files/documents to a temp file, and open that when
the viewer can't access e.g. smb:// or ftp://
locations. 
I try access a file at or windows PDC:
"Adobe Acrobat Reader" can't open "Rj45.pdf"
because "Adobe Acrobat Reader" can't access files
at "smb" locations.  No other applications are
available to view this file.  If you copy this
file onto your computer, you may be able to open it."

Nautilus ought to download the file to a temporary
location, and let the viewing application open that.



Steps to reproduce the problem:
1. Open Nautilus , browse a network
location(smb,ftp or similar) 
2. Try open a document with a non URL/GnomeVFS
aware application.

Actual Results:
Tells user to manually download the file to local
computer and open it.

Expected Results:
Nautilus could easily automatically download the
file to temorary storage and let the application
use that. Much easier for the user.

How often does this happen? 
All the time.

Additional Information:
Using Nautilus 2.0.6 here, Gnome2 as shipped with
Red Hat Linux 8.0
