Errr, what about applet downloads and RMI, neither of which requires
similar architecture or compiling capability at the other end? Are you
sure you are talking about something that even resembles java?
You distribute source code, and "JIT" compile it direct from source
code, yes. Just like Python or Perl or PHP or Javascript...
And yes, Java wasn't designed for this from the start, so the existing
compiler is too slow and heavyweight for this. This may even be
impossible. But the interpreted language space is pretty well covered
already anyway.
Please let me know when you've installed this mythical applet source
compiler on all the computers and phones in the world and then we can
continue the conversation about equivalent capabilities.
I guess what my point is here, is Java, in Sun's implementation, has
chosen to stand half-way between a native-compiled language and an
interpreted language.
And with very good reasons, applets and RMI being fairly obvious along
with things like cached jsp pages.
Which has resulted in it being mediocre at either
and ultimately just serves to inherit the disadvantages of AOT
compilation with none of the advantage (speed).
The main speed issue is loading the JVM which might happen once in
several months in a server environment and should be handled by the disk
cache and shared text in environments where it is reloaded often enough
to matter.

Except those don't have the same capabilities for remote execution.

I think you are missing a fairly vast library of available open source
java code.
