Actually one always can use
printf
C subroutine (or another C/C++ "standard" I/O functions to generate
any ASCII (or binary) output from within ROOT macro (or interactive
session) he likes. And then apply gRoot->Exec(" Shell command") to
launch something but ROOT (see root/tutorials/rootalias.C as
a patern).
I see no task here for ROOT team. It could be done on the user
level (ROOT-based application).
One can create for his users this system. It seems ROOT has
provided all features one needs to implement it.
I assume it is quite complicate to find an universal solution,
namely "format of datastream" to describe ANY C++ object but C++
itself.
With my regards,
