Why do you say it's a pain to implement? It's an HTTP+JSON API, and there's only one error code you have to care about:

If the value of the status key is 0, this is a valid receipt. If the value is anything other than 0, this receipt is invalid.

+1 Totally agree, it is actually pretty easy and worth it if you already have to have a server. If you don't already have a server, then it probably isn't worth adding one.
