I am required to setup a store that will operate through Tor and accept Bitcoin payments only. I know I can run the standard client on the server and make it connect to peers only through Tor. However, are there any other options available for handling Bitcoin side of things - hosting the wallet, creating accounts, receiving money and so forth? Do any eWallets or other services allow access through Tor?
Try using bitwasp. It seems to provide a lot of features you need. Try it and let us know if it works.
