I can see "advanced operating systems" consuming much more bandwidth
in the near future then is currently the case, especially with the web
2.0 hype. In the not so distant future I imagine a operating system
whose interface is purely powered by ajax, javascript and some flash
with the kernel being a mix of a mozilla engine and the necessary core
elements to manage the hardware. This "down to earth" construction of
the operating system interface will allow it to potentially be
offloaded onto a central server allowing for really quick seamless
deployment of updates and security policies as well as reducing the
necessary size of client machine hard drives. Not only this but it'd
allow the said operating system to easily accept elements from web
pages as replacements of core features or additions to already
existent features (such as replacing the tray clock with a more
advanced clock done in javascript that is on a webpage and whose
placement could be done by a simple drag and drop of the code
sniplet). Such integration would also open the possibility of
applications being made purely of a mixture of various web elements
from various webpages. Naturally such a operating environment would be
much more intense with regards to its bandwidth consumption
requirements but at the same time I can see this as reality in the
near future....
