Interactively Disable Local Keyboard and Mouse

I am aware of the registry entries, I have included them below.  Maybe you
could explain to me how to set the registry settings to accept a connection
upon time out.  According to the doc below, the timeout entry 
"indicates the number of seconds for which the Accept Connection dialog will
be displayed before REJECTING the incoming connection automatically"

The AuthHosts setting is, unlike the other settings, a REG_SZ string. It is
used to specify a set of IP address templates which incoming connections
must match in order to be accepted. By default, the template is empty and
connections from all hosts are accepted. The template is of the form:  
In the above, [ip-address-template] represents the leftmost bytes of the
desired stringified IP-address. For example, +158.97 would match both and Multiple match terms may be specified,
delimited by the ":" character. Terms appearing later in the template take
precedence over earlier ones. e.g. -:+158.97: would filter out all incoming
connections except those beginning with 158.97. Terms beginning with the "?"
character are treated by default as indicating hosts from whom connections
must be accepted at the server side via a dialog box. The QuerySetting
option determines the precise behaviour of the three AuthHosts options.
Local machine-specific setting. 

The QuerySetting allows individual users to tailor the degree of paranoia
expressed by the per-machine AuthHosts setting. It is a DWORD value ranging
from zero (maximum availability) to four (maximum security). The following
table indicates how the value affects the AuthHosts behaviour: 
0 - +:Accept, ?:Accept, -:Query 
1 - +:Accept, ?:Accept, -:Reject 
2 - +:Accept, ?:Query, -:Reject [Default] 
3 - +:Query, ?:Query, -:Reject 
4 - +:Query, ?:Reject, -:Reject 
By default, value 2 (Obey AuthHosts) will be assumed. Local & global
per-user setting. 

The QueryTimeout setting indicates the number of seconds for which the
Accept Connection dialog (see AuthHosts and QuerySetting options) will be
displayed before rejecting the incoming connection automatically. Local &
global per-user setting.

Did you read his post?  He noted, paranthetically, that you can set it up so
that if no one answers, it times out after a set number of seconds and lets
you in.

The registry settings you talk about will not work since the query option
will only give me access to the PC if someone is at the PC and using it.  I
do not want to access it then, I want to access it if no one is there.  If
no one is there, then no one can accept my request and I will not be able to
access the PC.

Since the makers of VNC thought of this, There is an option you can set in
the registry for a message to be displayed stating something about someone
is taking control of this system do you want to let them... (what is even
better is you can set it to disconnect or accept if it times out (no one is
