Bluetooth Profile Management

Hi,
I am newbie to Bluetooth Technology...
I have read the following:

"PalmSource provides a sample application—including source
code—for HSP that can be used both as a normal application and as
a persistent Bluetooth service application. Users can launch it as a
normal application, but because it registers itself as a Bluetooth
service, it can automatically launch in a thread in the System
Process when an inbound connection is detected from the headset.

The sample application provides the following features:

• Connections (the ACL link, RfComm connection, and SCO
link) can be establishes either from the audio gateway or the
headset.
• Connections can be released either by the audio gateway or
the headset.
• Volume control can be performed remotely, by the audio
gateway."

(The above text is taken from "Low-Level Communications.pdf",    page
number:117)

The sample HSP service application can be found in the samples/
Bluetooth/BtHeadset directory in the SDK.


My Questions are:
1.) I am not able to find the sample application described above. 
Any pointers?

2.)Is it possible to write my own Bluetooth Profile and replace it  with the
inbuilt profile? (As described above)
