Sorry it's a long one but is a rare & actual positive experience with cohabitation...
I recently experimented this with my panther chameleons. I took a receptive female and put her in with my male. They bred and bred for a week. Finally she decided to show gravid colors. However I left her in with my male because they were getting along. They both ate, drank, and basked at the same time. After the first week the male did not try to breed as most males will do even if a female is showing gravid coloration. While they had plenty of space, a 8ft tall, 5ft. wide, and 5 ft deep enclosure, the female seemed to always want to be by the female. I even went so far as to introduce another male into the equation and as expected he raced for the female. It was the next thing that threw me off. The female gaped and started to run and hide and the male who was next to her stood his ground and I immediately had to remove the intruder. After this encounter the pair went back to their daily routines. Naively I assumed he was protecting her girl but a couple days later I realized he was most likely protect his territory. She has since laid a clutch(while in the same cage as the male who for a change wasn't by her side) and is not yet producing another (2 months later)and the male has not attempted to breed her again yet. Both have either maintained/slightly gained weigh, when they need to be losing it because they are giant, and seem healthier than ever. I have tried this after a couple mating since then and have never had this same result. I even had a female start biting my male immediately after he got off her back. While they can cohabitate I would not recommend it for a first venture with chams. I like many other deemed it taboo for quite awhile and have found it can happen in the right environments even with the most aggressive of species. So now instead of having to have like 30 cages with chams to be fed and waters I only have to do it to 29. I do however still have her cage set-up just incase anything goes wrong with the pair. Like chris stated I think when a male is exposed to a female constant;y, no matter how much he initially wants to breed, after being around her for awhile and getting used to the fact she is there makes it less exciting to breed and they may not go as crazy upon sight of a female. I'm going to attempt to leave them together for 6 months and see if she becomes gravid again, if not I am going to have to remove her and reintroduce her a few weeks later and see what happens. so to answer our question If I were you I wouldn't but yes it can be done.
EDIT: Great link BTW chris. I have been looking for some info about the subject reiterating my results with a species similar to panthers aggression wise, veiled fits that profile perfectly. Oh and I hand feed/watch my chams eat their food If I put it in a dish for them so I know what they are eating and how much of it.
