Saving ISOs

[n3gwg]

Netboot.xyz users and developers,

First let me start off by saying thank you to all that make this project possible.

Consider if you will the person that places netboot.xyz image onto say a 256GB USB3 flash drive. It is their desire to be able to have a local copy of ISOs they might boot from on the flash drive (say they get the latest copy of Fedora and just want to save it locally to be booted from later before a new version is forthcoming). How difficult would it be to fold this kind of functionality into netboot.xyz in the same manner that Kali Linux (for example) allows for persistent partitions.
