Expediting Combat in IRC Games, Techniques to stop it dragging on Options

[ToreadorVampire]

Yet another new topic from me (I should do more work!)

Those who play in IRC games (and especially those who run them) - what techniques do you use to make combat smoother, and not take 50 mins of real time to resolve one combat turn? (I admit that was the team's second game session, and all of the players were new to the game at that point, we are a fair bit faster now).

Things I do:

• When players roll to attack, I request that immediately after rolling the attack, they post their modified DV and AP - ignoring successes from dodge roll (which I may not have made yet). This helps because I can just subtract [my dodge roll hits] + [my DR test hits] from their modified DV without having to ask them and wait for a reply. Also, it tells me the AP quickly, which I need to know to make the DR test in the first place.
• If someone is going for a called shot to negate armour, remind me when stating your AP, because otherwise I may forget and roll the target's armour (forcing a rewind and reroll, which wastes time)
• I try to make a map available on my website in advance and have a grid on it, so players can say "I want to move to somewhere near D7 and take cover behind that car" (and I can make "you sank my battleship" jokes)

But still I feel like we could be going faster. I wonder if anybody has or knows ways of:

• Tracking initiative in a publicly-viewable way, so players can see their turn approaching and be ready for me to say "You're up"
• Handling figure placement on the map - not like a full miniatures practice as is required in D&D, with AoOs and whatever, but some way that players can see where they are on the map, and see where the bad guys are, like how they're taking cover. What I guess I'm asking is if anyone knows any decent RPG map/minis services on the web that would work for SR?
• Anything else that online GMs do to keep the action flowing smoothly in their games

All ideas welcome, even the crazy ones (especially the crazy ones)
