Description
It would be nice to use 7zip instead of zip to distribute the nightly builds. I tried compressing the image: haiku-nightly-hrev33465-x86gcc4hybrid-vmware.zip (110MB) using 7zip and the result has only (59.8 MB).
Regards.-

It should be easy to put a link to 7zip home page on haiku-files.org with the corresponding aclaration that it is free, open source and is already ported to most OSes ( including Haiku =) )
Anyway I'll try to make a more formal analysis on expected compression gain.

Good news, here are the results:
7z shows an expected reduction that rounds 45.61 percent in comparison with zip format.

Build-O-Matic is capable of providing the same image file as one or more archive formats. The implementation is flexible and allows the builder to specify the compression binaries, options, and extension inside an archivers.xml data file. Then each jam target is capable of specifying which of the available formats to use for compressing itself. My only concern is the additional disk consumption on HaikuFiles. Currently, 97G + 97G + 60G are being used for raw/, vmware/ & cd/ respectively.

For some months, nightly images are provided in zip and tar.xz
The reason this was not done initially was because there is accessibility issues with 7zip. A normal .zip file presents a low barrier of entry for users of all experience on all platforms. Using bz2 would be fine for users on Unix-like OSes but I doubt that many Windows folk have ever seen that file type.
On the other hand, the compression is really awesome!
Perhaps the barrier can be lowered by making it very clear in multiple places that 7zip is open source (free) and can be downloaded via a link. A test could be performed with fairly computer illiterate users to determine the viability.
