Protecting mah program

- I have written a program, I want people to pay for it
- It is a type of program I don't expect hackers to have motivation to hack (it's a recipe program)
- If the program doesn't receive a valid activation key, it goes into limited trial mode
- The activation key is the SHA1 hash of the installation key + a guid I picked.  They must enter this key to get out of trial mode.
- The installation key is the SHA1 hash of the hard drive model + serial number.  They get this and must email it to me with money.
- I don't expect typical users of this program to know how to spoof the HD serial number (lol females).
- Did I do this right?  Suggestions?

It's the hard drive model + serial number, which doesn't change during reformats or any filesystem activity at all.  Actually, I think it would be more than totally unlikely that a housewife would share her key with a friend.

I know crackers aren't worth fighting.  I'd probably open-source it at some point in the future.

My license would be per-hard drive.

They can't even read.

Which is NOT your typical housewife.  Also, do you think a person with that ability will even be interested in this program?  I think it is unlikely.  If this was something gamers/hackers/programmers/4channers would typically want, then yeah I would expect it to be hacked to bits and hung out to dry in all warez realms.  I don't think such would waste their time with this.

You are in the gamer/hacker/programmer/4channer category and that is why you don't want to pay for it.  Me too.  I wouldn't pay for this program when I can (gasp?) write it myself, which I did.  But I'm seeking to exploit others that are not in this group.  Help me help you to help me not help others, okay?
