I use Java Applet for that purpose and connect directly using socket. I do this in my project "Internet bases control of real-time systems".
 
I would use a .asp page with some VB script in it. Have the VB script in the asp page interface to a DLL you create in VB with MS Comm 6.0 (serial port) or if your using a parallel port or a ADC / DAC card I would try something like NTport "www.uct.on.ca/":http://www.uct.on.ca/ .

An example of website does does something like this "xrobocam.ati.sl.on.ca/default.asp":http://xrobocam.ati.sl.on.ca/default.asp . This site only uses digital I/O but it could be done just as easily with analogs inputs.

I would vote for java too. For one thing you could do some "near" real time threading (I am assuming you're using windows which doesn't know squat about real time anything). Also, depending if you are going to embed the control, java will run anywhere.

We used a Java Applet to pull the Real Time Data from the server.I had to make a server program that acquires the data and serve the requests. The protocol between the client applet and the server was SOAP.

We also developed a better and more scalable solution in which the applet ask for certain tags once, and the server pushes the RT data into the applet client in a timely fashion.
