I certainly have. JAI isn't exactly intuitive.

I certainly do. I basically check to see if the user provided one and only
one image and if so call 'loadMultiImageTiff' with the indices of the
desired images:
(in SpotImages.mergeColorImages()) :
HashMap<String,RenderedOp> images = loadMultiTiff(red,index_635,index_532);
sourceImages[0] = images.get("635");
sourceImages[1] = images.get("532");
I'll clean up my code this weekend. Would you like me to send you a diff of
some sort? I wrote a Test class based on yours and heavily altered (in
parts) SpotImages.java.
I certainly have data I can 'lend' you for testing (please email for a url).
I'll also ask the Molecular Devices people for a dataset that we can put
into the svn for testing.[1]

Great.
Another point:
The 'zip' that contains spot images isn't a zip. It looks like a zip, but
this[2] is what I see when I try to open it in osx. Can you provide a hint
as to how to open it?
Thanks!
