how many devices can be registered for iOS Enterprise programme I am working in a big organization where I want to distribute application with 300 different devices. 

I came to know that iOS Enterprise programme is available for such a big in house distribution , 

But I want to know how many device can be registered with such programe ? 

With simple developer programe with ad-hock profile we are able to register  100 different devices that I know but with enterprise I do not have any idea.

If any one know then please let me know.

thanks in advance...
I'm pretty sure it's unlimited, tho I couldn't confirm it from any official source. There are reports of people using it for way over 300 devices, tho, so you should be fine.
