Thanks for the replies.
I have been diligently checking for answers to my concern about using the Domperidone, and luckily, I was able to speak to an IBCLC here in my home town. She was immediately supportive of my interest in using the domperidone, and gave me a SNS to "play with", so I can get used it.
She confirmed that many women use the dom without problems, and there are many pediatricians who are ok with mothers using it to help breastfeed their children. In other words, she was more than enthusiastic about the idea, but cautioned that she wasn't encouraging, just informing me that the use of dom is ok, as we have seen through all the literature here. She also recommended the pharmacy in Vanuatu, so I think I've got the ball rolling to help convince my DH that this might be ok.
I know I'm on the right track, because I felt much "better" after having spoken to this woman. I trust her advice, because I happen to work at the hospital where she works, and she would be more likely to discourage me, if she had any reservations.
She also pointed out that they give dom to mothers whose children are born prematurely, and are in the NICU, but they want to pump and store breast milk, but it's difficult for them due to stress and not having the baby at the breast.
So, I'll be discussing this with my DH tonight!
