Allow servers to push add-ons to clients?

[Mumbo]

Hi there!
Are there any plans to let Online-Servers require players to have certain add-ons installed, and/or ask them to download them when they try to join the server? Xonotic does a similar thing - if you try to join a server where a custom map is running, you have to allow the game to download it to join. For STK, this clearly wouldn't work out - as it would delay the start of the game heavily - but forcing the download when a player tries to join should work out.

So, to be clear about what I have in mind. Assume I have a server running where the map "Museum" and "Lost Chasm" are installed, and I activate the option "Require players to install Add-Ons". Upon joining, the player who doesn't have these maps gets a message like
"This server requires you to have following Add-Ons installed:
-Museum
-Lost Chasm

Download | Cancel"

Any chance for such a feature? =) It would greatly improve the support for custom maps - as things are now, you can be sure that in a game with 6 players or more somebody has no add-ons installed.
