iPad's In The School

In about a year, I will begin heavy discussions with Apple on what the next lease at my day job looks like.  I’m 100% sure I’m going all iPad with the students, but I’m really pondering if I could do 100% with teachers (office staff would still have a Mac on their desk).  Here is what I’d need:

1. Renweb (School management software) iPad app (they already have iPhone apps, so I’m hoping that it is coming)

2.  Ability to convert network based printers to AirPrint (probably with this device)

We’d have to rethink some work flows, but I think our teachers would love the ability to have a smaller device to carry around and have it always be on (without always worrying about battery life).
