No, this was all an idea I've had for a while, but never did anything about it. 
 I'm pretty sure the Galaxy developers are not interested in anything this 
locally-centric, and I don't blame them.  It ought to be something outside the 
Galaxy build completely, because Galaxy is meant to be system-independent.

What I meant by 'joint user/galaxy directory' is a directory that is owned by a 
user, but that the galaxy user has read (and possibly write) access to.  This 
is entirely possible given either a well-informed user population, or an 
iron-clad suexec executable.

The mechanism I alluded to is a feature by which a user can upload a directory 
of files all at once.  There is a configuration directive in universe_wsgi.ini, 
user_library_import_dir, that allows non-administrative users to upload an 
entire directory of files into a library.  The directive identifies the base 
directory, within which subdirectories named as the galaxy user login (email 
address) are searched.  The user_library_import_dir directory is owned by the 
galaxy user, and the subdirectories are owned by the user, but group owned by 
the galaxy user.  A user will copy files to the subdirectory, login to galaxy, 
switch to their library, and upload all the files in the directory into a 
single library folder.

There isn't much documentation about it in the main Galaxy wiki, so forget 
that.  I haven't enabled it in our local production site, and I haven't played 
with it in a long time.  I'm pretty sure that the files are not removed after 
uploading, and a user is free to re-upload the files again and again, so it's 
kind of quirky.  Also, if the files are not readable by the galaxy user, a 
bizarre and unhelpful error is thrown.

If this functionality could be extended and elaborated, it could do what you 
want.  The user_library_import_dir requires that the user's login in Galaxy 
must be identical to the the user's login on the cluster, and that the 
permissions be kept correct.  Typically users have no idea what is going on 
with their permissions, so what are you going to do?
