Flame me (in private) if I am wrong about the following outline:
 
Win 3.0 Standard/Real modes use temporary files and a temporary
subdirectory (if one is so designated) for purposes of swaping
information out of RAM and for making interim "saves" (in some
applications, e.g. PageMaker, Calendar, Clipboard).
 
Win 3.0 Enhanced mode has Standard/Real mode functions plus the
option to designate a perminent swap file, whereby contiguous
sectors on a disk are preallocated for use as a swap file. Temporary
saves (i.e. *.tmp) are still stored in a designate temp subdirectory
or the root directory (if a temp directory is not designated).
 
A diskless workstation would have to set the swapfile option off
or set a perminent swapfile to a RAM drive and designate a RAM drive
subdirectory as a temp directory. Unless I am mistaken the swapfile
and the temp files must be considered separately. I imagine that 
a swapfile remotely located would degrade apparent speed of operations
more than a temp subdirectory remotely located. With limited RAM and
large applications and/or numerous applications Win 3.0 would probably
have to employ a swapfile more often than an application would have to
employ a interim "save" file (i.e. a *.tmp file).
 
In order of preference:
 
1) Disable swapfiles in enhanced mode or somehow establish a swapfile
   in a RAM drive (if possible and/or reasonable).
 
2) Designate a temp subdirectory located in a RAM drive for any Win 3.0
   mode.
 
You will use up RAM in either case but you will preclude excessive use of
remote disk space. 

What happens if an application does not have enough temp space? I 
believe PageMaker displays error messages. Lack of swapfile space in enhanced
mode usually prevents you from loading data or an application (out of memory).
