Fast tethered shoot with 5DII and WTF-E4 (FTP)

Hi

I want to do fast tethered shooting. "Fast" for me is if the image was displayed on the computer screen within 1-2 seconds after I took it. EOS utility and LR3 beta are nice but slow because everything you shoot (JPEG/RAW/RAWJPEG) is transferred and the RAW which I really want takes way too long. Also tried sRAW which is faster but not fast enough and often you want full resolution.

So I really like the FTP option of the WFT-E4 / 5DII combo because it allwos me to shoot RAW and JPEG and only transfer JPEG via WFT, making it very fast.

However, as I have the thing configured now, I only end up with the files very quickly on my computer but not with them being displayed quickly/automatically.

So is there

a) a FTP server that launches a viewer for every new file that comes in (like IrfanView can be called from EOS utility) or

b) a fast image viewer that can be configured to watch a directory and always display the latest image that came in?

Or is there another, better way of doing this?

Chris
