Since XRPs are not IOUs and not self-issued, I don't think you can "trust" anyone for any amount of XRP.
You trust people in terms of external currencies like BTC or USD.
sorry, good point i meant 0.003 BTC trust this = about 100XRP
on the current BTC/XRP RIPPLE trademarket
No trust is required to transact in XRPs.
Actually this should be called Propagate XRP/BTC
