ASP.net VB.net Getting unique information about a computer

Hi. The following code seems to find just the name of the PC from an ASP.net site
 How do I find other information that is unique to that PC?


Dim way1 As String = System.Environment.MachineName
            Dim way2 As String = Server.MachineName
            Dim way3 As String = System.Net.Dns.GetHostName
            Dim way4 As String = My.Computer.Name
            Dim way5 As String = System.Net.Dns.GetHostEntry(Request.ServerVariables

These activeX are already on user machine and you can access them via javascript (if user permit).
You can use following scenario insted:
1. Create 'ProductGenerator' WinApp for download on your site. This app will gather info from client computer (using System.Management or system.Net class for example) and convert it into some code-like (GUID, for examle) form
2. User send this info to you (via e-mail or just filling ASP.net form).
3. You home computer or ASP server contains a code which encrypt some text ('My app is cool' for ex) with above GUID (as a  crypto key)
4. You send encrypted key (password) to user after (s)hi paid for software
5. Your main app available for download have same code as #1 to get and convert system info as well as symmetric algo to decrypt password. Then check decrypted string - if it's 'My app is cool' - run full code, otherwise - run demo code

ASP.net controls server-side, not client side machine. Though you can get remote_addr, but for IPv6 it may be useless. You can get some info via ActiveX like shell/wsh/WMI, but user can simply switch ActiveX off...
