WiFi hotspot Software

I am designing a WiFi hotspot network. Each hotspot will have a captive portal. My question is is any one else using DreamHost servers for this type of traffic?
I would like to use WiFi Gator MX software which requires ‘proxmox’ to be installed on a server. Does anyone know if it is possible to install this to my DreamHost account?
Thank You for your time.

In this sort of setup, the portal software typically runs within the WiFi network. Running it externally (on DreamHost servers, for instance) will be difficult.
