Having done a bit of research on Ripple after stumbling upon this thread last night, it seems very very interesting. It definitely seems like it'll complement, rather than compete with BitCoin. From what I've read, it seems like an extension of MtGox.
I understand how the IOU's will work, and it's quite an interesting idea. But I'm not going to focus on those, I'm just going to write what I interpreted from reading about the system to see whether someone has any other interpretations. Please guys let me know if you think I've hit it bang on or whether you've interpreted their information differently.
Basically the impression I get is that the Ripple system intends to become a holding (bank) and exchange market for every currency (fiat and crypto) in the world, whilst also creating their own cryptocurrency (XRP). Basically, I can send GBP to Ripple, and with one click of a button, I can instantly convert (or send to another Ripple user or shop that accepts Ripple) this in USD, BTC, XRP, Yen, or whatever currency I want with no fees involved. And I can deposit/withdraw any currency I want WITHIN the Ripple system with no need for 3rd party exchanges. So basically, as I said above (an extension of MtGox) Ripple is a massive currency exchange market who intend to make profit only off of their own cryptocurrency (XRP), which they're hoping will become worth something (which it should do, as it will become a central medium of currency exchange).
And on top of this, they have the 'contacts' list which can be used to allow people you trust to borrow a maximum amount from you whenever they want.
This, is a fucking outstanding idea and I'm very surprised someone hasn't thought of something like this before. Instant payments/conversions to any currency within the system, obviously it'll take a few days to bring money (fiat) outside the system.

And this won't kill BTC, it will complement it. Why do I think this?
BitCoins have a value, because of the black market mainly. XRP's, do not (currently) have a value. And won't do unless (like BitCoin) people perceive them as worth something. In order for XRP to replace BitCoin, they would have to become widely used in the black market, which I highly doubt will happen because look at the identity checks MtGox requires. If Ripple takes off though, XRP could gain a value based on the fact that every Ripple user has access to it, and it will be the 'central' unit used for currency exchange within the system.
Definitely going to follow this development.
This has the potential to kill PayPal. And if that happens, through Ripple, BitCoin will gain in popularity.
I will admit, I don't currently use MtGox because of their requirement for identity, and I don't really want my identity associated with BitCoin. However, Ripple intends to serve a completely different purpose to BitCoin. I would use Ripple, without a doubt.
Very excited to see what happens here.
your 99% right.
the bit that i find most unique and powerful is that if i held GBP and you held bitcoin we can swap them and leave them held within ripple, without banks involvement, we can then use those funds for further trades spreading the types of currency we all hold without restrictions.
i dont think the ripple concept is based on loans in the manner that BTCJam consider loans. but more on the concept of reserves and allowing / trusting other people to manage X amount of my funds for me.
but for my personal use i wont be involved with loans, i would only consider the currency transfer concept without banking rules/restrictions/fee's
