John,

Do you know about creating an indirect buffer with the current source
block? This indirect buffer will be in ESS mode, and any changes you make
will be in the original source block when you exit the indirect buffer.

I believe C-c ' in a source block will activate the indirect buffer. There
are variables controlling how the resulting window is created.
