Will it be possible to install applications published outside the App Store on the iPad? I want to tether my new iPad to my Droid by using PDANet which must be downloaded from the vendor's website to the iPad. I've read a few articles and forum posts which indicate this might be possible but I can't imagine how it would work with the iPad. I really hope so because I've just cancelled my 3G order and replaced it with a WiFi only order.
