Can orocos RTT do a communication like Ros's topic mode ?

Hi all,

I have few questions about orocos,

1. Does orocos RTT support a communication style like Ros's topic, the naming bus mode ? 2. When orocos been used in realtime os like rati or xenomai or what, which lib can be used in realtime task ? I mean I think that it's impossible to use boost in kernel mode, boost may like with user-mode lib depending on libc.
