direct links of old sources may well be a few messages off.

We are currently in the process of finishingre/refining the ROADMAP
document, and discussing the algorithms. This discussion takes place
on the drbd-dev mailing list.

Maybe you should suggest your boss to contact office at linbit.com ?

Probabely LINBIT can offer him a solution to the requested features 
within his schedule.

* Get used to UML (user mode linux)
* Start kernel hacking
* Start reading the DRBD source.
* Understand the items on the ROADMAP document, 
  a lot of them depend on the previous ones.

PS: The ROADMAP document on the web is very outdated by now, 
    get the latest version from the trunk in SVN.
