That brings me to the other claim on your website: "free(ish)". As Gateways and the intermediaries will be for-profit entities, I don't see how this will be free(ish) at all, even if the base XRP cost is near-free everybody else will charge money. It will possibly be cheaper than other ways of sending money, but I don't even see how that's guaranteed.
It's not guaranteed. That's a forward looking statement.

Some projects like Bitcoin make claims based on what the software actually does at the time without giving you an honest assessment of whether it would actually scale or even be feasible to run for the typical user in the future[1]. Others like Ripple make claims based on what might be true in the future if the system does indeed scale to a larger userbase.
Then there are serious projects which tell you what they actually do and at least attempt to publicly verify how well they scale before evangelizing their software.
[1] This doesn't hold for bitcoin's claim of "anonymity", since it was never true at all, but I don't remember whether the official site ever claimed that or if it was just glib fanboys on the forums.
