we're lucky, we're too far south for the bigger spiders [still training kids not to play with funnel-webs though], but our pest control company sprayed for DropBears as part of a deal for termite and spider control and we've seen none of those fury buggers since;)
thats not such a bad idea dropping the power to sections of the city or just unplugging sections of the network late at night. when you stop getting some sort of response from the device you can narrow it down. done this before when we had a denial of servcie attack coming from an unknown device in a network of 10,000 users in the asia pacific region. in this case we had admin access to the various routers to isolate the subnets. but swtiching off hardware can do the same. even if it's outside the city's durastiction, at least there is a trail to follow. it's not that hard to track down a device but if in this case the business is functioning maybe the cost of taking down parts of the system is not worth it, yet.
if it's not possible to install enough exhaust fans to get the hot air outside or into the office area where the building aircond can deal with the heat then you are going to need an airconditoner and a good way to drain water away from the dehumidfying process.
With out knowing anything about your environment i go by a simple rule, for every watt of power you need about a watt of cooling.
check the power supply's on each device, server, router switch, ups etc etc and count up the watts, you can use Amps just find and online calclulater to convert. This will tell you the power of the system need to cool, split air cond used for a home will do about 2KW (kilowatts) a fully ducted system used in a house will do about 20kw. I am using house system for rough comparison only.
so now you have an idea of heat output, the 2 options I would use is either 2 cheap aircond units with each one capable of meeting the KW requirement, that way if one dies the other will keep everyting going and you can have cheap maintenance, or one good quality systen with high level of maintenance with extracter fans for back up. don't forget the extracted hot air and moisture has to go somewhere!
one thing to keep in mind, using the power supply info assumes running all systems at 100% untilisation, which unlikely but does give you worst case scenario, so if you know none of your server go over 50% cpu, for example, you reduce your required kw of cooling by about 25%.
i know there are proper formulas to calcuate exact KW/BTU/AMPS/WATTS etc etc, but when I am just trying to figure the best stragety the "it takes a Watt to cool a Watt" is a quick way to estimate what its going to take and draft up a plan.
That simulator was great, I nearly lost a whole lunch hour to it, it's brilliant how something so simple can be so addictive.
As for landing on Mars, just bring Mars to us, Virtually, with all the data from all those droids now and into the future there has gotta be enough to recreate it in a place like Second Life where anyone can explore it first hand virtually....and add in some sort of immersion suit for a total experience.

can someone pass me the SPF9000000000+ sunscreen please.

Kudos. ================= There is no grand scheme, life just wants to be, so, let it.
