Don't know if I can do this, Please HELP...

This is what I need to do. Hopefully someone can help me. I am trying to find a way for my customers to download a piece of software and not have to configure anything. I don't want them to have to change router or firewall settings. I think the software needs to do a reverse connection. Then I need our technicians to be able to connect to their PC. Sort of like Logmein.com. I have been told in other forums that Logmein.com uses VNC or UltraVNC. Can someone please explain how this works and if it will work at all.

Yes, you are referring to a reverse connection where you would use a viewer in listen mode.

I am hoping someone can send me in the right direction. I am building an internal system for our hospital for our help desk. Here is a general scope of the project.

Definition of Terms:
1) Server: means the Linux or Windows Server
2) iHelp365 Server: refers to the server we need built for our clients and technicians to connect to.
3) iHelp365 Client: refers to the piece of software our clients will download on any Windows operating system. It should be small in size and the client should not have to or be able to configure it at all. It should be able to go through any firewall or router without configuring the firewall or router, which means we will have to use an HTTP tunnel.
4) iHelp365 Viewer: refers to the Java web plug-in that our technicians will be able to connect to the iHelp365 server and select an iHelp365 client to connect to. It should give us complete control of the iHelp365 Client.

Overview:
Most importantly, this system should be able to handle 50 technicians using the system at the same time. The iHelp365 Client should connect to the iHelp365 server through the HTTP tunnel. The iHelp365 Client should be able to go through any firewall and router without having to configure them or disable them. Basically I think what we are doing is a reverse connection from the iHelp365 Client to the iHelp365 Server through the HTTP tunnel. The iHelp365 Client should be connected at all times (as long as the user is on the internet). When the user requests support from the iHelp365 system the iHelp365 Client will tell the server ok, this user requested support (each user will have a unique ID in a MySQL database as well as a username and password) then the iHelp365 Server will ring all available technicians PC’s (iHelp365 Viewer). The first technician who answers the call will gain remote access through the iHelp365 Viewer.

iHelp365 Server
I am hoping we can develop a solution for a Linux box. I am not sure what this will be built in but we need to connect it to a MySQL database that I have already built to verify user accounts for customers and technicians. Please advise me on what else we should do with this. This should be like the logmein.com gateway.

iHelp365 Client
This should be a small piece of software that the customer downloads on any Windows operating system. It should configure itself to see the iHelp365 Server. The iHelp365 Client should be displayed in the system tray and when a user clicks on the icon they should get a menu. Menu item 1) Visit iHelp365 Website. The iHelp365 Client should be able to be visible through any firewall or router through an HTTP tunnel.

iHelp365 Viewer
The technicians will use this to view the customers screen and take control of their PC. The iHelp365 Viewer should allow complete control including file transfer, chat, and remote control. This will be a browser plug-in developed probably in Java.

Examples
Please see logmein.com, gotomypc.com for examples of the iHelp365 Client and iHelp365 Viewer.
