Hello Keith,


Something is wrong with the way you seem to be using the term
"ad hoc" network.  It doesn't have to be a single link.  There are
lots of reasons to have a multihop/multi-technology ad hoc network.

Thus when I see:

I wonder just what you might mean. IP is very good for forwarding packets in a
multihop network.


There's nothing wrong with using the packet format on an ad hoc network, the
problem is it's the expectation that apps have that IP equates to Internet
access.


I thought apps were supposed to care about end-to-end data exchange, regardless
of whether the data is exchanged over one or many links.


 An ad hoc network is a different beast than the Internet and you
can't expect apps in general to transparently work on both kinds of network.

That's news to many people in the [manet] group! Why not??

At the very least you need an API to allow apps to declare whether they work
on one kind or both.  And the default needs to be the Internet.

I also can't understand this.
