As a temporary hack I've done the following.
I created a directory CACHEDIR,
and put it at the start of TEXINPUTS.
Then any input file requested in TARGETDIR is linked
to a file with the same name in CACHEDIR.

============= in lib/site.h =============

#define TEXINPUTS  ".:/usr/local/lib/tex/tmpinputs:/usr/local/lib/tex/inputs//"

=========================================

=========== in lib/ourpaths.c ===========

!#define TARGETDIR "/usr/local/lib/tex/inputs"
!#define CACHEDIR "/usr/local/lib/tex/tmpinputs"

...

boolean
testreadaccess (name, path_index)
  char *name;
  int path_index;
{
  string found;  
  
  make_c_string (&name);

  found = find_path_filename (name, path_dirs[path_index]);
  if (found != NULL)
! {
!   if (strncmp(found, TARGETDIR, strlen(TARGETDIR)) == 0) {
!     char cmd[256];
!     sprintf(cmd, "ln %s %s/%s", found, CACHEDIR, name);
!     system(cmd);
!   }
    strcpy (name, found);
! }
  
  make_pascal_string (&name);
  
  return found != NULL;
}
=========================================

Just an idea ...
