Currently yes, this is the only standard way to do it.  There was a JEP to do 
"Tree Transfer", but it was not well received, mainly because it doesn't 
solve the bytestream reestablishment problem.

The JSF Council was not interested in this feature (also known as 
role-reversal), so I created it as an extension and optimized it beyond what 
we had originally discussed.  It is documented below as Fast Mode:

Psi has been using this for over a year now without problems.

The same URL above also describes a Multiplex mode, however it is just an 
idea, I've never implemented it nor tried pushing it as a standard (yet).
