You're talking about Java and JavaScript I assume?

Here's a list of the limitations:

* Everything has to happen in a browser.
* Mobility is limited: It is server-to-client only.
* Only virgin code travels. Once code runs, it is stuck in one machine.
* Quite restrictive sandboxes. Java only offers a choice between
"allow very little" and "allow anything". We want to be more flexible
there, ultimately. Granted, this is a thing of future improvement.

We want to go far beyond the browser as an execution environment.
