I've never tried, but I hear that it's not particularly difficult.  Timing
is the biggest issue.

From Dirr:

    Cuttings taken in January rooted 92% in sand:peat in 20 weeks after 
    treatment with 100 ppm NAA for 24 hours.  Cuttings from 7-year-old
    trees collected in January and treated with 20 ppm IBA rooted 70%
    in 8 months.  In 32 weeks there was 43% rooting of untreated cuttings
    taken in August.  

He goes on to say that root cuttings are best if the cuttings were allowed
to soak beforehand, and low resin content seemed to be correlated with
high rooting.  See Waxman, PIPPS. 28:546-550 (1978).  Feb - Mar. and
July - Aug. were the best of times.
