VERY well said, Erika from Tulsa!
You have hit the nail on the head, so many times, but I will repeat them:
>The problem with these suggestions is that it only addresses the problems of communication between devices on a one-way street.
Exactly right. People are not getting the original question.
> I have a 3rd generation iPad and I can do this with a 30pin to VGA adapter.
Correct! Nothing genius about that!
>The problem no one is addressing is ... a way for the Smartboard to communicate with the iPad.
Spot on! That's what I was saying way back in the early days of this thread, but got shot down by...
> It is not helpful when comments are shared like "the smartboard is not post modern technology and should be gotten away with."
Exactly! That is not helpful and shows elitism - something Apple should avoid projecting.
>How can we receive input on the iPad from a smart board?
Ah! The CRUX of the matter... And it *IS* possible... If Apple allowed it. Technically, there is NOTHING stopping this to work, as iPads allow input connections from BlueTooth devices like Keyboards. And I have seen a video of a jailbroken iPad having a BT mouse connected to it. Here is a link to see it yourself:

Likewise, there are Smartboards that use BlueTooth to talk to the computers, and the interface is just like a mouse interface. So technically, there is NOTHING stopping this from working... Except Apple don't allow the connection of mice to their iPads.
Other tablet devices do allow it... Works fine on just about any Android device and the new Windows 8 Surface device even has a BT trackpad in it's cover - very clever. Not that I am recommending you use any of those... But maybe Apple might change it's philosophy when the MS Surface starts making inroads into education because the Surface WILL work fine with your Smartboard.
I just hope Apple wakes up BEFORE the MS Surface gets a toe-hold. It would be a very sad day for me if I heard a mass purchase of Surface devices in schools because they can work with your Smartboards, and iPads miss out.
Good luck... Sadly, the answer at this moment is - You Can't do it because Apple don't want you to, and so this answer leads to: You will need to look at other devices, if this is a critcal issue.
Please Apple... Allow mouse input to the iPad.
