vRO Powershell Script Repo

I've been tinkering with running powershell scripts from vRO via a powershell host, and have a couple of questions on the matter:

1. It appears that script to be run on the powershell host cannot be a UNC path. Is this actually the case, or is there something I'm missing.

2. Are there any common ways that people typically host a repository of powershell scripts for vRO?
