My suggestion is to finally support 7ZIP as an archive format. Why?

1. Because it's supported by countless archive tools, like 7-Zip of course, but also by WinRAR, TugZIP, PeaZIP, ZIPGenius, IZArc, PowerArchiver, jZip, and more.
   
   
2. Because it achieves the best compression.
   An example: I managed to compress an ECMed image of "Secrets of the Pyramids" and its sub channel data, which has together a size of 537MiB, down to 76MiB. Compare this to compression with ZIP, which achieved with the same files only 174 MiB, 24MiB over the 150 MiB limit.
   
   
3. Thanks to the huge compression benefit compared to other archive formats, it may save a lot of server space.
