Why should you rule?

But seriously there are some features that reqire a PIN number, I have
never set it up so I am not sure how far that extends.

But think your problem through. How does the backend know who is
holding the remote when you are setting up a recording or deleting
one? How do you authenticate with a remote? Should you need to
authenticate every keypress? How long before the authentication times
out?

You may think the system is ridiculous, but it works for many people.

They don't use all the same settings. Its per frontend hostname
though, not per user. Take a look at the settings table in the
database:

mysql> describe settings;

+----------+--------------+------+-----+---------+-------+
| Field    | Type         | Null | Key | Default | Extra |
+----------+--------------+------+-----+---------+-------+
| value    | varchar(128) | NO   | MUL |         |       |
| data     | text         | YES  |     | NULL    |       |
| hostname | varchar(255) | YES  |     | NULL    |       |
+----------+--------------+------+-----+---------+-------+
3 rows in set (0.01 sec)

See how each setting has a hostname associated with it? Thats why you
WILL get problems if the database thinks two machines have the same
hostname.
