[galaxy-user] import local files

Hi, to reduce traffic when importing big dataset into our local galaxy we would like to copy directly from the fileserver (which is accessible from the galaxy server via NFS) into galaxy without moving through the users desktop computer. Is there already such a tool by chance? At a glance I could only find import.py which imports only from a predefined set of files. So if no such tool exist what would be the best starting point? upload.py? For security reasons I would restrict the import to a certain directory. Anything else to keep in mind? regards, Andreas
