Students work - extending ode

[Madars Vitolins]

Hello!

I am student, new for ode and I have planned for my student's work to 
extend ode, add some new standard support.
What is current ode status for:
1) BPEL4PEOPLE
2) BPEL4CHOR
Is there is there something implemented and how hard it would be for 
person to implement it?
If these are hard bit's is there anything missing in ode from:
WS Reliability
WS Reliable Messaging
WS Addressing
WS Transaction
WS Security

and how hard would be these to implement?

Thanks a lot in advance,
Madars
