Many DAW's (Digital Audio Workstation) such as Cubase, and DSP "plug-ins" have special software protection schemes. Cubase uses something called eLicenser[1].
Another popular, niche product that has proven difficult to fully crack is a program called Pro Tools, created by DigiDesign, now owned by Avid. It uses a protection called PACE Anti-Piracy[2]. Many expensive pieces of software require unique hardware, either a security dongle or some other external device.
Seems like a novel idea. My suggestion would be to change the design of the website. Make it vertical instead of horizontal --- i.e. input above the output. That way it'll display properly on an iPhone. Clearly you have the technical chops... Now you need to find a good designer to work on your bootstrap theme!
-Focus on the "Sales Process". You won't go anywhere without first identifying the need(s) of the prospect and making sure they know that you understand their need(s). Then determine who the decision-maker is, so you don't waste your time selling to the wrong person.
-Approach prospects via email AND phone, until you've figured out which method they prefer.
-Don't give up until you've received a clear rejection. Offer rebuttals to their objections.
Stick with those rules, and work to refine your pitch. Persistence is key!
