I've determined that a weredwarf fortress is unfortunately nearly impossible because of the way combat is processed. After a huge ammount of failed attempts and fort "rebellions" I've come to the root of the problem. When Mr. Weredwarf attacks the dwarf he is attempting to infect he engages in combat. In a perfect world he would bite him and flee, but his bloodrage compels him to maul continuously until either he untransforms, or the other is dead. Where it gets sticky is that the werecreature engages in grappling, which, after transforming, the grapples are maintained. This causes the dwarf to deem the other dwarf to be a foe, and will finish him off after the transformation is complete. This brands the finishing dwarf as an enemy of the civilization. The only time when it works is when there is no grappling or down and dirty wrestling, but the mauling goes cleanly. I've discovered after numerous trials that this is nearly impossible to achieve, and the prospective spawn is either killed for wrestling with the weredwarf, or the weredwarf is branded and torn apart. It is due to these technicalities that I believe a wereskink fortress is impossible, and in my current attempt the werecreature was eventually branded and ripped apart by the populace despite his stupendous regeneration and protection.
tl;dr
Werecreature fortress nearly impossible
Dwarves can detect newly infected prospects, and attempt to eliminate them
A werecreature can be a part of your fortress, provided he is kept away from prospect din-din during his time alive
Werecreatures undergo spontaneous regeneration upon transformation, even of nerve type damage that would normally be permanent
Lycantrophy is not heritable through birth
Lycantrophy isn't even totally heritable through a single bite, and numerous dwarves suffered a bite with contagion occurring
Finally, werecreatures respect each other enough that they don't try and eat each other.
If somebody does want to create a werecreature fortress, they'd have to use unskilled newly infected dwarves to infect new dwarves, and if there was ever a bad batch they'd be screwed, because skill would begin to develop and remove the possibility of a safe infection. Or at least that's what I suspect.
