montage - pack images

Hi,
It'd be really useful for j2me development if montage had two things:
1. pack mode
Pack images in as tightly as possible
1b pack mode with overlap (if it is safe, overlap the images i.e. if two images have a line of white pixels at the start and end).
2. output the filename, x, y, width, height for each file placed in the new image.
With this it would be a very useful tool
Cheers.

The closest we have to pack is
-mode concatenate.
Add
-verbose to your command line to list the image file names and their offsets. You can also use this command:
- identify -verbose montage.miff

I found that you can overlap images, if somewhat tricky, by using negative offsets for the -geometry parameter.

Hm, yes I tried concatenate, but when the images are different sizes big gaps appear negating any size benefits.
For the moment, I'm looking at just using montage on groups of images the same size.
Just tried verbose, and it doesn't give pixel coordinates of the images; I assume their added left-to-right, top-to-bottom.
Is there anywhere I could post an RFE for the packing? I'm looking at integrating this into a build environment, so the idea is to not have to manually adjust images geometry etc.
(Or does anyone know of some other tool that could do this?)

Update: Found this python image packer which I'm having a look at

Update2: This doesn't do the efficient packing I need

By offsets I really meant placement - is there no way to see where it's put the files, or do I have to calculate it myself ?
Heres some output I get:
