Remote Assistance File generation - using .net class / code

All
One of the issues we face when helping our remote workers is that they are
(9 out of 10 times) behind a router. So when they initiate a Remote
assistance call they always do so via email and then our Help desk folk
manually alter the file using notepad withe correct IP address and also
default gateway. (which is often not 255.255.255.0 but can have another value
in place of the last zero digit.

I am wondering if it is possible to programatically generate the
RcBuddy.MsRcIncident file. it is in XML format so I am thinking it is
possible. THe only issue is the encrypted password. Does MS offer a .net
component or class for generating a remote assistance file.

For example could we use the same encrypted password each time in a new file
whcih already has the correct IPaddress and default gateway information.
THen there is the issue of the expiration time. Is this configurable
programatically?
essentially We would like to write a program to generate the Remote
assistance file and at the click of abutton by a remote user end the file via
email to our help desk

Aay suggestions or ideas are always appreciated.
