Allow PDF for one user and expire after 1 year? 2

[m1a1911]

My company produces ~300 page medical reports that we deliver in PDF form. We feel we are losing money because some companys purchase one report under a single license (instead of a corporate/multiuser license) to save money and share it with their entire company anyway.

Is it possible to have both of these features:
1) Have a PDF be locked to whatever computer opens the file for the first time, so it can not be opened from another computer?
2) Have the PDF expire after one year so it can not be opened?

I currently own Adobe Acrobat 8 Professional and Adobe Acrobat 9 Professional. If there is additonal software/addons that can be purchased to acheive both these features I will pay for it. Please advise!

Kind Regards,
Kevin
