What are the work visa requirements for foreigners marrying a Thai and working in Thailand?

First of all - just want to say that this group is fantastic. Thanks to all those who keep answering questions. I've been silently learning more every day. There is seriously no better place to learn about visas in Thailand than here.

My scenario:

I am about to marry a Thai and move there with him. I am hoping to find work in Thailand or have an arrangement with my current employer to work remotely in Bangkok. With that said, I am unsure about the work visa situation. I do know that as a spouse of a Thai that I would still need a non-O to stay and a work permit issued by my employer to work. However, is it possible that company A issues me a work permit but I actually work for both companies A and B? Would this be a violation? Any workarounds for the quota problem for work permits?

Many thanks for your help in advance!
