I'm in no position to give opinion here, because I have no plans on using that at the moment, but probably I will later. I would say the community loves OPTIONS. So, why not?
I've looked at your website and it seems you want to approach the community commercially, why not ask Tom to put you in a Usergroup? Do it like what Spriter does, I bet it gives the impression of how serious you are. I bought Spriter on a whim simply because they are somewhat associated with Scirra, it gives me confident in purchasing their product, even though I don't have needs to use them extensively at the moment.
So far we have gone 50/50 on the plugins, Admob is free and Parse is paid. This IAP plugin would most probably be free as there already exist a bit more advanced paid version.
About the "Usergroup", what is that exactly?
