yes it's possible.
all of accounts are saved with options
you can 'save options to file',
open hfs.ini and find the lines named 'accounts='
all of accounts are crypted but you can copy and replace this line on the other files hfs.ini (existing accounts will be replaced by the copy)
only accounts are saved , permissions are stored in the vfs, you have to redefine them for each resource of the vfs.
