Your right it was aimed at Webferret.
As for your deal:
Do you blame them? Your asking THEM how to better protect your code.
I kinda see where your coming from, but it's not their problem. Another wasted ticket (from their viewpoint) IMHO.
Typically business are not going to go out of their way, spend their man power and money to help you like that.
They have a product, they're there to sell it, and support it. It'd be like if I went to a restaurant and asked them how I could take their burger and make a better burger than what they have. Yeah, they'll get right on it. That's how I see it.
A response would be warranted one way or another in my opinion, since they go out of their way to provide free patches and other freebie tools and such. And they have answered questions in the past pertaining to 'different' ways of doing things since the product has a number of settings you could use. So if there was a means, I would have expected some kind of a comment such as "look at such and such parameter in chapter 5 of the user manual".
So it didn't seem odd of me to ask , since I am not asking them to remake the program, but seeking advice as to pre-existing configurations and functionality they already provide in the product. Like for example would --binary be better than --ascii in this case? That kind of thing.
I expect any professional business to reply with a response, even if canned, otherwise it fuels the mind of the paranoid. And lord knows there's going to be plenty of paranoid freaks revolving around a product of that nature

My general feeling is that ioncube at the moment is the best possible detterant for PHP priacy. Primarily because those who would try to steal the script costing less than a thousand dollars, is 1) not going to bother to pay someone to decode it, especially if the price of the product itself is lower than the decoding fee. 2) Most people who would have the know-how to decode the script without a fully automated tool, is likely also able to easily write what I have to offer, and most who would need a few days to figure it out, don't really want to bother. and 3) In the last 3 or so years that I've searched for a pirated copy of zend or ioncube, I have only found automated solutions freely downloadible for zend, but not for ioncube.
So far as 'deterrents' go, ioncube seems to be the best at the moment, plus if nothing else offers a slight acceleration boost due to being in bytecode format .
