I was wondering if this license is:

• self defeating
• just a clone of an existing, better established license
• practical
• any more "corporate-friendly" than the GPL
• too vague/open ended

and finally, if there is a better license that achieves a similar effect?

I wanted a license that would (in simple terms)

• be as flexible/simple as the "Simplified BSD" license (which is essentially the MIT license)
• allow anyone to make modifications as long as I'm attributed
• require that I get a notification that such a derived work exists
• require that I have access to the source code and be given license to use the code
• not oblige the author of the derivative work to have to release the source code to the general public
• not oblige the author of the derivative work to license the derivative work under a specific license

Here is the proposed license, which is just the simplified BSD with a couple of additional clauses (all of which are bolded).
