Hello Lucien,
Here is what I have on V. storri breeding and husbandry to give you an idea on their feasability of good captive results:
BREEDINGS:
Eidenmuller, B. 1994. Herpetofauna 16(88):6-12.
Eidenmuller, B. and H.-G. Horn. 1985. Salamandra 21(1):55-61.
Horn, H.-G. and E. Stirnberg. 1981. An unexpected new generation in a terrarium Varanus storri. Salamandra 17(1/2):55-62.
CAPTIVITY:

Alot of people have worked with this species, and quite good data here-in to begin your information gatherings. Feel free to email me about further details and if you want copies, we can work on that too...
cheers, Happy Holidays!
