I downloaded this software because of this thread... I tried it for the 30 minute trial period and found it to be simple to set up and use. I bought it. I used it to run RFC with my Shammies, and had no problems. 64 bit vista support. The cost for the first license is $40, that covers two machines. Each additional license (machine) is $20. You can use paypal or your credit card.

This is the first software of this kind that I've used, so I don't have a comparison to other programs or hardware. I just know that it does what it says it will without any bugs... so far.

It's what I use to control my 10 characters over 2 computers.
