Believe it or not, but when I wrote 'some confidence in Bitcoin' I meant literally Bitcoin and not any particular exchange or rehabilitation project.
Right now, Bitcoin does need as much good public relations as it can get, and a quick and full compensation for the small-fish victims of the MTGox disaster would constitute good PR indeed.
A large group of angry customers who get back their funds means many less people who have (somewhat understandable) motivation to actively criticize and oppose the whole Bitcoin project.
Besides, the idea of compensating smaller creditors with some preference over bigger creditors appeals to my sense of justice. (Despite the fact that I do not belong to the former group).
The idea of prioritizing small clients is not bad by itself, but that could perhaps be proposed to the liquidation court. AFAIK, Japanese liquidation law already establishes a "socially just" priority scheme: first any unpaid salaries and benefits, then actual creditors (banks, suppliers, landlords, contractors, utilities, etc.), and lastly investors. I don't know where MtGOX clients would fit in this priority ranking.
The Sunplot proposal obviously cannot change the priorities of employees and actual creditors; the court could not possibly agree to that. It apparently inserts the new owners and managers, as well as the expert investigator (Mr. Karpelès?) into this ranking,
before the clients. Isn't that so?
There is also the question of what should count as the claim of a client against MtGOX: (1) the account balance he had at some point before the final shutdown (when, exactly?) according to MtGOX's internal ledgers, or (2) the total amount he deposited, minus the total amount he withdrew? It is known which approach the liquidators will follow?
Since it is possible that the ledgers may have been altered with fake trades, or that some clients may have used insider knowledge or other fraudulent means while trading, approach (2) would seem safer, besides being arguably more just. (If we were to trust the crowd analyses of the leaked MtGOX database -- which of course can be itself fake -- Mark and several of his friends are among the largest BTC balances.)
Perhaps the implicit aim of the Sunplot proposal is also to ensure that any distribution of coins will follow approach (1), rather than (2) or some other scheme that would exclude suspicious balances?
