Calling an Access form or message from a .net application

I would like to open an "announcement" form on a receptionist PC when a clie
nt arrives.  We use a Windows Mobile 2003 PDA with a VB.net "smart applicati
on"t o check the client in when they arrive at our service facility.  The PD
A form accesses a SQL db an
d updates their vehicles data.  The client then goes into the reception area
.  How could we have a message display on the receptionist's PC based upon t
he arrival event in SQL.

The receptionist has Access 2000.  Could we use this, or is their a way to h
ave the PDA "call" a form on another (the receptionist's) PC?
