ASICMINER-PT is not owned by different people, it's owned (operated) solely by Burnside.
You can transfer ASICMINER-PT to Havelock, where TAT operates a passthrough (details:

Any ASICMINER-PT shares not transfered in this way are converted to direct shares when BTCT closes. Once you have direct shares, you can either hold them or transfer them to BitFunder (or Havelock, I suppose, but then you might as well take the direct route).
