So unlimited processing is your core strategic advantage? Is it just the psychological effect of "unlimited" that's important? If so you could have a soft-limit (think bandwidth-throttling). Or describe the actual limit in language that makes it seem bigger. The business model of "promising" more capacity than you actually have is pretty common, especially with cloud storage provides. To some extent every SaaS does it. As long as you do the math and structure pricing accordingly you're fine.
