A program like Skype with auto answer for iOS?
So I found another program that does almost everything and that is "usable" in my case, as Skype is not. 

Babyphone 3g

Pros:


It has the auto answer feature.
The camera can be turned off when not used.
If the connection is bad, it offers to take pictures.


Cons:


Video is only one way (big down) but sound can be both ways.
The "babything" design which makes it look unapropriate for me when it is the best I found.
Not free (and probably pay for each separate device you want to connect, have to check that)


I am not sure I should answer my question or edit my question in that case...
