A next-generation package manager called Nix provides a simple distribution-independent method for deploying a binary or source package on different flavours of Linux, including Ubuntu, Debian, SUSE, Fedora, and Red Hat. Even better, Nix does not interfere with existing package managers. Unlike existing package managers, Nix allows different versions of software to live side by side, and permits sane rollbacks of software upgrades.

"Also, I suspect rpm/dpkg can be used in the same way to parallel install most things, but the distributions do not do that due to the above problem and assosicated maintenance costs."
Indeed. It's a fundamentally dim way of doing things. One historical objection (it's a giant waste of disk space) is getting less important these ways, but it doesn't make it any less of a maintenance nightmare (or less of a huge waste of memory).

By allowing side by side installation of packages instead of just upgrading them, would this not be a security nightmare?
