About the certification programme, please visit:
http://source.android.com/compatibility/overview.html
About the device's unique ID, it is probably impossible, since Android is open.
And looking at it philosophically, why do you need unique device ID for?
Licensing issues? Look at PC software industry and licensing issues
there. The most restrictive models fail anyway and you just have to
live with it.
Even on fully controlled iPhone, developers get their software stolen,
since people jailbreak. You will have thousands of devices out there
that run Android and your app and never passed any certification. Just
look at China's grey mobile market, which probably is of the size of
Europe's certified market.
Look at it more positively instead. Developing countries have massive
potential. Maybe never, but maybe soon people there will get rich
enough to pay for your app?
And lastly, think of the actual price of software with relation to
people earnings. Markets only convert the price using actual currency
exchange rates. To some USD0.99 is still a day's work.
