Comparing with the public list, only 4 balances match redeem requests. If ru0chen (position 6) is typical, this list shows balances at time of redeem request, but shares have subsequently been sold. ru0chen is listed as requesting 2000 shares redeemed, but only holds 500.
I am on the list, and the requested amount is different from what I have now. I also sold some shares after the request, but not much. I still want to redeem all of the shares I own. The shares I sold were below face value, so the buyer hopes to gain a little bit extra in addition to the dividends.
I believe that there will be more redeem requests, especially if btc continues to go up in price.
I'm fine with direct shares, and I don't need dividends every day. Once per month would be totally OK for me. That way Graet won't have to send dividends to 100 or so addresses daily.
Trading can also be implemented with direct shares. Maybe with PMs between buyer and seller, then directly through Graet, in that case he can charge a fee (for example 0.5% or 1%). And yes, that would be totally OK, since BitFunder charged 1% too. So if you decide to make shares tradable, Graet, it is completely justified to charge a fee.
