Except as expressly permitted in this Section 2G, or except as otherwise licensed by Apple, you agree not to use the Apple Software, or any of its functionality, in connection with service bureau, time-sharing, terminal sharing or other similar types of services, whether such services are being provided within your own organization or to third parties.
where the quoted section allows remote access by a single device, remote viewing by a "reasonable number" of devices, and remote access to a separate desktop session by a single Apple-branded device.
So buying/leasing a hosted Mac for development is fine, but renting remote access to a shared Mac for development is right out unless only one person (or two, with the second connecting only from Apple-branded devices) is using it at a time and virtualization is not used.
