Several points:

The /record feature actually works, just that no console (and no way to bind keys to brute-force record/stop) puts it out of reach.

Other things may be much harder, such as leaning which would likely take a bit more work (there's a bunch of new stances in the game, i.e. riot shield, akimbo - nfi how the animation system works but those weren't in CoD4, at least)

At the moment you can get a semi-accurate ping readout up to 135ms by editing the multiplayer config file and setting the bars to 9 and bar division to 15ms. That's 'good enough' for me, although of course a numerical display would be much less of a blatant insult to intelligence.

Edit2: Just remembered, regarding graphic tweaks. Apparently at the moment re: r_drawdecal 0, instead of turning off surface decals actually makes some walls completely disappear. (Hey, whaddya know, an in-built wallhack!) If this is an engine rendering problem patchable with a new exe, that'd be fine. If it's actually some new methodology of creating maps (i.e. the problems exist in the map files) then we're probably sunk a little in that regard.

IW.net really, really needs these features:

- Auto-balancing (you listed this under non-IW.net but since being locked to teams is matchmaking related...)
- The ability to vote to change the map, both in-game and in-lobby
- The ability to vote for a new host
- The ability to queue for a friend's game when its full and enter as a slot becomes available (FIFO, game tells you how many are queued, if there are others) If the friend leaves that room it should instead throw you into his party for re-queueing.
- The ability to toggle on a confirmation dialog box for "Find game" which asks you if you wish to join the room based on the ping to the host (and other players in the room since IW.net can be a d*** and swap hosts for no reason) and the current map.

I know that IW.net replacing ded servers on their part is supposed to make the game more user-friendly, but the above features can do nothing but add to the end-user experience overall. Their inclusion will make their matchmaking service 0.2 as enjoyable as having ded servers instead of 0.1.
