I really like ajaxplorer for hosting files for others, and for having multiple users who need to acces directories on your server (like for a webserver with multiple users).
But I'd recommend owncloud if it's just trusted family users because it has some cool picture / ect.. addons. I don't know if anyone's gonna package this up cuase you gotta run a webserver with php to run it so it might be easier to just install it yourself from packages.
I'd look into installing a webserver with php support like apache, or nginx+php-fpm, and just pointing it to the latest files from owncloud.
