Hi Kern,
I already read dev manual, and it's extremely outdated.
I cloned bacula git repo two weeks ago and had been studying the code since
then.
Last week I accomplish to compile bacuka trunk (Branch-5.1) with sucess and
finish my sandbox dev environment.
This week I'm recruiting fellows from my local community and some of my
students to start a code team for this feature and possibly others.
When I have the first usable patch it will be posted here. Until there, any
minor progress will be discussed here. I'll use all your suggestions and
guidelines for this features, and you all will be informed of any decisions
to make.
Best regards,
