i am absolutely sure that you do not have access from your computer to clients spread throughout the network. it should not be allowed. else you could collect all data of all cumputers connected to the internet.

if you are able to put little "satellite"-apps onto each client you want to monitor (for example in intranet), then there should be a possibility.
1.1) every satellite detects the data and writes it into a database (db, file, ...)
1.2.) ... sends collected data to a server containing more intelligence

2.) activeX-control and webbrowser? (microsoft-TECHNICs...;)

Both of those requests can be handled by the c# WMI interface.

For available on the local box:
mgmtScope = new ManagementScope("root\\cimv2");
mgmtScope.Connect();
System.Management.ObjectQuery oqr = new System.Management.ObjectQuery("SELECT * FROM Win32_PerfRawData_PerfOS_Memory");
ManagementObjectSearcher query1r = new ManagementObjectSearcher(mgmtScope,oqr);
ManagementObjectCollection queryCollection1r = query1r.Get();            
foreach(ManagementObject mo in queryCollection1r)
       {
       return (UInt64)mo["AvailableBytes"];
       }  

Here's a description of what ManagementScope() looks like for remote boxes:

For CPU usage, you'll have to sift through these to decide which you want:
