When is the scheduled date for this feature?

There is not a *date* per se, but if you see the label Milestone-1_4_RC, that label
is intended to communicate that we plan to implement this feature for 1.4.

Is there any way to have the common GWT bootstrapping code in another js?  And the
actual module functionality in a separate js.  This way, if we have two modules to be
attached to a page, I don't repeat the common js.  I would have to include only one
of the common gwt js, and then the releveant module js files.

Actually, it's better if you don't.  The most significant speed factor in most cases
is the sheer number of HTTP round trips.  We plan to run the nocache.js files through
a compressor/obfuscator in the upcoming release, so they should get a lot smaller
than gwt.js currently is.  Plus we can optimize them a bit for the specific module
being loaded, instead of having to make it completely generic.

In a future release, what we really want to do is process your HTML file and just
inline the selection script straight into the outer page.  That is, replace your
<script src="com.example.foo.Foo.nocache.js"/> with the actual contents of that file,
to remove another HTTP round trip; then when you GZIP the outer page it should get
really small.

thats awesome.  

Regarding the sec para, i would like to have an option for having it as inline versus
a standalone script.

A basic implementation has been checked in as r623.  It still needs to be vetted, and
the naming agreed upon.

This now fixed as of at least r763, if not before.

Changing to Fixed status with GWT 1.4 RC release
