Have a look to my thread:
https://bitcointalk.org/index.php?topic=524622.0Section collateral for details for some hints.
If you'll be able to implement successfuly this option, you'll definetly have me as investor (at least to give a try).
And for sure, many others from BTCJam wil do the same.
Good luck.

We would love to implement this functionality. Providing LTC collateral will be trivial, but I'm going to dig into CEX.io and CryptoStocks.com; I would be really thankful if I can take about 20 minutes of your time to ask you some questions about how you use CEX.io, CryptoStocks.com and the general ways you currently solve the problems around lending. You can contact me via Skype (ozpowermo), Google Chat (kgantchev) or you can just use the chatbox on the bottom right corner of our website to talk directly with me:
www.bitlendingclub.comPlease note that if you do use the chat box on our website it will show me your IP, browser, and OS. If you're concerned about privacy, then don't use the chat box. In any case, it would be very helpful if I can talk to you and we'd love to build something that's actually going to work for the lenders. Please let me know if you would be able to find some time to spare.
Best Regards,
Kiril Gantchev
