The RRP version of RepRapFirmware is lacking several features and fixes in the more recent releases of my fork (at [github.com]) and Christian Hammacher's fork (at [github.com]), so I suggest you start from one of these. Several people have built my fork, with a little help from me. Christian's fork may be easier to build because it has its own Arduino core included.
What modifications will you be doing?

RepRapFirmware already supports mixing extruders and multiple heaters and extruder drives for a single print head. So you may not need to modify it. Your biggest problem will be generating gcode to specify the mixing proportions. You may be able to use a standard slicer followed by a gcode post processor, especially if the mixing proportions are constant.
All forks of RepRapFirmware for the Duet support the web interface.

If you prefer building using command line tools as opposed to an IDE such as Eclispe, then there is a fork of the dc42 branch which can be built from the command line using scons and the gcc arm toolchain from either Arduino 1.5 or 1.6. It's a fork I've been using for a port to RADDS and Aligator boards of the dc42 branch. I keep it up to date with dc42 and it has no functional deviations from dc42. It does have some structural source changes so as to support building for multiple platforms (Duet and RADDS at present).

The problem is that mixing proportions will not be constant within a print. There would be regions of different material proportions trough put the material.

There also might be need for driving screw within the nozzle, in order to produce good quality mix/blend. Any suggestions on that ?

Perhaps use another stepper motor to drive the screw, as if it is another extruder drive?

Mhm, I clearly see what you mean. The other issue is Duet Extension Board, is there any need to do any changes in your version of 1.09 or RepRap's 1.09 in order to use printer with Extension board ?
