Given the zero Interest fee's level I would be more than happy to give this service a try.
Brilliant idea for quickly building up some positive reputation in the forum too btw
I would be interested in securing a loan for 0.002 BTC for 7 days whenever your satoshis slush fund has been replenished.
Please remit the 200k sat's to the following BTC address 377hAHU9K5Jei5FgLfkkBV17uSQ3K5V3rs
And let me know which return address you would like payment to.
I look forward to hearing back from you and see how well this experiment works out for you.
*Note, the above listed BTC address is an exchange address...if you plan on implementing the signed message verification process mentioned by @coupable then I will need to change this address to one from which I can sign messages from.
