not for OpenSG 2, it will have a new OSB reader/writer (actually already
has, but its disabled by default). The reason is that the current
default OSB IO is not thread safe.
I don't think it currently supports your use case, but it should not be
impossible to implement it. I'll put it on my todo list, but dare not
giving you an ETA.
