Sync CMDS Without Bungee

Plugin category:
Administrative

Minecraft version:
1.10

Suggested name:
SlashSync

What I want:
Ability to run a command on one server and have it sync on other servers simultaneously.
Command must be run on all servers as the user who executed it ( For global chat / mail / ban purpose )
Plugin will be installed on all bukkit/spigot servers.
Bungee Perms can not be used as login system allows Bungee commands to be run before login.
Commands can be grouped in config and a static permission per group defined.
Only 3 static groups required, commands within the groups are dynamic.

How will it execute:
SQL: Not sure if this is possible with SQL.
Web Server / App hosted in Apache?
Bungee: Using the proxy without using Bungee commands / perms.

Ideas for commands:
/sync <command>

Example Usage:
( Setting rank with GM server wide )
/sync manuadd user admin
( Setting the time server wide )
/sync time 12:00

Ideas for permissions / config:
Commands should only be available with /sync if they are listed in a group.
Custom permissions per defined group example:

group-permissions:
# Per Group Permission Nodes
- moderator
- slashsync.moderator
- admin
- slashsync.admin
- server
- slashsync.server

groups:
# Groups And Commands
moderator:
- tempban
- 123xyz
admin:
- banip
- 123xyz
server:
- restart
- 123xyz

messages:
prefix: '[SlashSync]'
no-perms: 'No Permission'
sync-error: 'Sync Error'

Requirement:
Urgent

Thank you for taking the time to review my request, please keep in mind I am not an expert in programming.
Kind Regards

It's plenty possible with SQL (specifically MySQL), but it won't be 'simultaneously'
Since connecting to a database, reading, deleting, etc can become resource intensive quickly, and can lock up the db if done too often, it would have just a slight delay (say something like a few seconds at most if you have a repeating task in every plugin).
Unfortunately, I can't do this as I am working on several other projects, but I just wanted to say that it is possible with MySQL if nothing else.
