Still, the physical server itself and the bandwidth cap (from what looks to be softlayer?) are limits on what's available. Your "unlimited" plan certainly seems to be better than those from most providers, but it's still proper terminology to say that it is unmetered.
Saying that something is unlimited just seems like a cop-out for providers that aren't willing to share what their actual limitations are (2 TB hard drive, 100 mbit port, etc.)
There's truly no reason for us to switch out one similar term with another, especially when both terms provide a nearly identical meaning.
Although I see your reasoning behind making such a switch, you must understand that we are trying to market our services towards the general hosting consumers, rather than a single niche market of knowledgeable developers. We do try to operate a very open and developer-friendly hosting environment, and a simple term will never change our current stance. There's just more general consumers in the world than there are developers, and our hosting network is here to accommodate everyone.
We'll certainly be sure to provide more public and easily accessible information, as well as a clear explanation of what unlimited hosting is, and how it differs from infinite and limited.
We do have this information publicly displayed on our website, although it may be masked by complicated terms such as 'quotas' and 'resources' which most general consumers may not properly understand, so a clear and concise example of our true limitations and server specifications is something we'll have to create. We could possibly include a sort of easy to read list that outlines our hosting environment, and what 'unlimited' means to us.
Maybe even a rewrite of our Unlimited Policies document, so it's not as technical.
If you have any more feedback or suggestions, please be sure to reply back. We rely on our current and potential customers to provide us with honest feedback and information. Without you guys, DRS wouldn't even exist.
