Softaculous is fabulous. It has so many scripts that can be installed quickly. But I have problem downloading the scripts for the first time or when new version came out for that scripts.
I dont know softaculous infrastructure, but isn't it great if softaculous has several servers to download from. you can load balance it, based number of connections or even detect where is the closer server to download.
I think the NOC Partners would be proud to provide a server for softaculous.
Just my 2 cent
