The main portal is http://www.data-raptors.com/cherani/index.html. The language home page is http://www.data-raptors.com/cherani/tradespeech.html.

Yes. There are actually two part of Cherani Station, thousands of miles apart: one is at the free-fall (zero G) point: most cargo goes through there. The section where most of the people live is the counterweight, farther out, where centrifugal effects provide the equivalent of gravity.

If the people on the planet were willing/able to come off the planet, they wouldn't need to contract with someone else to build and run the station, so they could keep all the profits for themselves.

It's literal. Shayanans have 4 limbs with 4 digits on each limb. They use hexadecimal, but 64 is a nice round number because it is a hand of 16s.

At some point I mentioned that there are froglike aspects to Shayanan reproduction, and that the Imperials may have got it wrong when they decided which Shayanan sex was male and which was female. OK... when the Imperials arrived on Shayana, they found a species with basically 2 sexes. Sex A has an intromittive organ and a somewhat more itinerant lifestyle. Sex B has a more settled lifestyle and is apparently viviparous in a marsupial sort of way. So the Imperials decided Sex A were the males and Sex B were the females. However, the intromittive organ is technically an ovipositor, and the 'females' are the sperm producers. And the species is technically ovo-viviparous and marsupial rather than viviparous and marsupial. Shayanans are warm-blooded, etc. but in reproductive terms they are amphibians who have solved the problem of living in sea water without having their tadpoles pickled. Both the seed-pouch (where fertilization and initial development takes place) and the milk-pouch (where lactation takes place) are environments where the developing infant is protected from external salt levels. I don't know what the criteria are for deciding that a baby looks or tastes too wrong to raise. Shayanans know what their babies are supposed to look and taste like.

More or less, since the highest status individuals usually have the spots at the center of a community that are safest for raising the babies. When things are right for reproducing, the highest status non-lactating Sex B individuals in a settlement undergo a hormonal shift that makes them ready to be impregnated and adds pheromones to their grooming oils that tend to attract non-lactating Sex A individuals (and induce the beginning of ovulation in them) and catalyze the same hormonal shift in lower status Sex B individuals. Gravid Sex A individuals put out pheromones that get peoples bodies ready for lactaion. (Grooming each other with the oil from their grooming-oil glands is a major factor in Shayanan social interaction, and important to the health of their skin.)

No, not the seed-parent, the pouch-parent. The hormonal effects and bioenergetic drain of lactation tend to suppress ovulation and rut. Lactation is enormously expensive biologically (in Earthan mammals, too).

Yes. Because she only accepts the seed of one of them.

Because the 'males' are the ovulators: making eggs is biologically expensive and takes time (a couple of weeks, at least, from the time the pheromones hit). Two ovulation cycles puts you past the end of this year's mating season.
