Please provide more details about "I can't use my programs with that" 
and "symlink didn't work at all" because here any program can use files 
on the mounted directory at /run/user/<uid>/gvfs and even the a link 
testing it here.

What will not happen is the link to automount, you will always need to 
do the gio mount thing, Maybe from a login script.

The idea of these FUSE based tools is for the drives to be mounted on 
demand. The problem start with programs that don't use the current 
desktop way of mounting things, so they don't know how to show these 
mounted directories on their Load/Save dialogs. So I get why you want 
some kind of way to have a known directory inside the user home for 
these files.
