[Ubuntu 13.04] Bluetooth serial brez super user

-u user The -u (user) option causes sudo to run the specified command
as a user other than root. To specify a uid instead of a
user name, use #uid. When running commands as a uid, many
shells require that the `#' be escaped with a backslash
(`\'). Note that if the targetpw Defaults option is set (see
sudoers(5)), it is not possible to run commands with a uid
not listed in the password database.

If you place an ampersand (&) after your command, the deluge-web process will be detached from the parent (and the sudo process will exit):

sudo -u User deluge-web &
