However, what I think will be an issue is that you need to use two layers of quotes to pass a json string over the command line. I expect this will cause problems on windows, because quoting works differently there.

That would be both shorter and completely avoid quotes. I don't think is should make parsing this signtificantly more difficult than what you have now.

Okay, in that case passing them on the command line is definitely the way to go.
