Hi Terry,<br><br>As Adam suggested, the 3Di load balancing code has much of the functionality you request. We can already clone a region and specify for each copy how much it should update. We haven't implemented the scenario you describe (an active region with a standby region that you could switch do), but it is just a matter of extending the GUI and making small extensions to the current code. <br><br>So it is no technical problem, but is it worth doing? Who do you think would be interested in this functionality? I could do this, or direct someone to do it, if it is useful, but if it ends up not being used I'd rather use my time on other things.<br><br>/Johan<br><br>----- Original Message -----<br>From: "Adam Frisby" <<a ymailto="mailto:adam@deepthink.com.au" href="mailto:adam@deepthink.com.au">adam@deepthink.com.au</a>><br>To: <a ymailto="mailto:terry@usfastweb.com" href="mailto:terry@usfastweb.com">terry@usfastweb.com</a>, <a
