How to go for entrepreneurship but be employable

I think this is my first post, so Hi, great forum thanks for everything...

I am going to apply to a few top-10 programs in a month and am just now starting my essays.

Ive read that AdComs can see a really good applicant, and then read his or her essays and feel like the applicant is unemployable because he or she is dreaming, drifting, lost, and/or hasnt really researched post-MBA goals - subsequently "dinging" the applicant.

I would like to be honest and indicate that I am primarily interested in the school's entrepreneurial management curriculum (Wharton, NYU to name a couple). I have a ho-hum start up business at the moment, and military background.

I plan on writing (the truth) that I am interested in the EM and *also* some other management curriculum, and that post-MBA I am primarily interested in management in startups (the school region's VC portfolio startups), but as a backup if this area is dried up/unattractive in 2 years to join an established management team or MC firm, capitalizing on skills and networks gained in "the other mgmt curriculum".

Basically my questions are:

how much more specificity should I provide here?
does this appear like a solid approach, or will I likely be labeled an unemployable drifter?
what kind of employment outside of a consulting firm do management tracks lead MBA candidates?
what is a good research platform for looking into where MBA grads are getting jobs given specific curriculums?

thank you!
