One thing I have wondered about is compression of text for iMode.
At a max of 9600 baud, you would think you could get some significant
gains by compressing text on the fly between server and keitai. Maybe
they already do that internal to their network, but I haven't heard much
about it. It seems like you could write a very small unzip algorithm
in the iAppli, to effectively up the throughput of text to the phone by a 
factor
of two or three, assuming the performance of the phone KVM is reasonably
fast.

But of course this only does you any good if you can customize the
browser on the phone somehow. So that's another reason to either have 
either the web browser written
in Java, or else a servlet engine in the phone which can run concurrently with
the phone's built-in firmware browser, and can talk to it.
