Yes, it is possible to make a 1394 DV sink, but DV transmission does not 
yet work for everyone. It seems to work for most PAL users and for one 
of my NTSC cameras. I have a good lead on the problem and some failure 
case devices to work with. Currently, it depends upon video1394, but 
video1394 is still a rogue device. I plan to make my replacement devices 
official. Also,  IEEE1394Writer::FillBuffer() in Kino's ieee1394.cc 
really needs to be moved into video1394, but that will require some 
ioctl interface changes as well. This particular method also appears to 
be responsible for when DV export fails. Therefore, I tend to recommend 
waiting for the new devices. However, there is always something to be 
said for moving ahead with what already exists just to get something out 
that some people can use.

Sorry, but I only do this work as a part-time hobby in the late evenings 
and weekends. For DV sink, check out the above referenced Kino method 
because it computes the necessary ratio of empty to full packets for the 
timing of DV transmission over 1394.
