There's really not any magic to this. You can create a disk image with Disk Utility. Put the stuff on it that you need, and then convert it to a compressed read-only image (again, with Disk Utility).

Answer 3

It's actually pretty easy. You just need to compose some hidden files. Easy way to do this is to just copy someone elses and change to suit your app.

For example, if I mount the MonoDevelop DMG, then I see:

atom:MonoDevelop fak$ ls -al
total 40
drwxr-xr-x   8 fak   staff    340 Nov  4 14:03 .
drwxrwxrwt@ 10 root  admin    340 Nov 10 21:33 ..
-rw-r--r--@  1 fak   staff  12292 Nov  4 14:03 .DS_Store
d-wx-wx-wt   2 fak   staff     68 Nov  4 14:03 .Trashes
drwxr-xr-x   3 fak   staff    102 Nov  4 14:03 .background
drwx------   4 fak   staff    136 Nov  4 14:03 .fseventsd
lrwxr-xr-x   1 fak   staff     13 Nov  4 14:03 Applications -> /Applications
drwxr-xr-x   3 fak   staff    102 Nov  4 14:02 MonoDevelop.app

Here we see .background that is a directory with a PNG file (the background). The app itself (MonoDevelop.app) and a link to /Applications.

The .DS_Store contains the window size, icon positions, etc. Just setup a directory and use the .DS_Store from it.
