I agree that adding this functionality to the osgtext::Text  would be

It would certainly not be more efficient, having to mutex access is
one sure way to add performance bottlenecks, there is also the issue
of data coherency - with one camera capturing one version of the text,
and the adjoining camera capturing the updated version.

The OSG is designed around single threaded update, multi-threaded
cull-draw, if you break this usage style then you are one your own -
you have to mutex (and even then its not perfect as above) or
multi-buffer again which is not ideal.  Just updating in the update
phase and you get no problems.
