yesterday I received this reply from ZT by PM which I'm sure he won't mind me quoting here:
You need to contact Bitcoinica Consultancy for this, and make sure you outline all the losses you incurred.
I started the swap system under Bitcoinica LP's approval and I was a full power representative at that time. However I did not have financial incentive - I can't touch a single cent of your swap money.
OK, now I need to think about this & how to proceed, I don't actually really even understand it, any helpful input would be welcome, many thanks ZT for responding, so it seems though that Bitcoin Consultancy which I now guess is called Bitcoinica Consultancy were not the owners & operators until after Zhou Tong's promise of the 22nd March 2012 to refund for swaps, but that he had already secretly sold Bitcoinica = Bitcoinica LP to T. Seale's investment group & was at that time effectively an employee of them
"Bitcoin Consultancy was first retained to perform a comprehensive security audit on March 27 and they became owners and operators of Bitcoinica LP on April 24. As General Partner, they have exclusive legal authority to manage the company." - Quoted from tseale speaking for the investment group that took over from ZT
I believe that when they take over the company, they should continue the unresolved disputes with customers. I designed the system because someone asked me to, and I gave the promise on behalf of the company because I had power to do so and it's consistent with Bitcoinica's usual dispute resolution attitudes.
If the amount is not large, I think they will honor. Otherwise you may need to explain very carefully to make it reasonable.
