Dear Rick,
Please allow me to address the licensing part.
1. There is no expiry date in any of our permanent license files, Domain, IP, SMB, Developer, Redistribution... Only our free trial version has the expiration mechanism. CuteEditor has been free upgrade since v1.x 6+ years ago and we don't plan to charge for v7 upgrade in 2010 either. If you were our v1 license owners from 6 years ago, today you'd be able to download latest v6 and simply put your v1 license file in to make it work. That's why you can't find upgrade charge, support charge or any other hidden fees simply because there is none :)
2. Your client can purchase a developer license and grant you the rights to use it. As long as there is only 1 developer under covered by this license at any given time, we are fine with it. However there is a chance you qualify for a lower license option:
A Domain license allows the control to run on 1 domain/subdomain name, ie http://news.domain.com or http://intranet or http://192.168.0.1
A Small Business License allows 10 such names
An IP license enables all the domains/subdomains hosted on this IP@ to use the control.
All license options are good for
http://localhost. I'd highly recommend Small Business License as it's the most popular choice among our customers. Out of the 10 names, you can use one or two for the internal dev server ie.
http://intranet while keep the rest for your production servers.
Questions?
