Transferring CUserCmd from server to client

[mayonnaisemay]

Hello. I'm having issues with the title. I don't believe net messages take anything but booleans, tables, ints, strings, and entities; and CUserCmd is not any of these. I tried setting Player.cmd = Player:GetCurrentCommand() in a shared file, but it still only worked for the client, and I was not able to retrieve it from other players. I need to do this though, because I'm trying to make a HUD that displays what keys a player is using.
My current code(again, this is in a shared file):
hook.Add("StartCommand", "may_keys_startcommand", function(ply, cmd)
ply.may_cmd = cmd
end)

if CLIENT then
CreateClientConVar("cl_showkeys", 0, true, false)

hook.Add("HUDPaint", "may_keys_hudpaint", function()
if !tobool(GetConVarNumber("cl_showkeys")) then return end

local may_keys_target = LocalPlayer()

if LocalPlayer():GetObserverTarget() and IsValid(LocalPlayer():GetObserverTarget()) and LocalPlayer():GetObserverTarget():Alive() and (LocalPlayer():GetObserverTarget():IsPlayer() or LocalPlayer():GetObserverTarget():IsBot()) then
may_keys_target = LocalPlayer():GetObserverTarget()
end

Any help would be very much appreciated. Thanks.
