More on WiFi

My tablet's working fine now. I've moved on to a new toy, a new Ipaq (with built in Wifi, bluetooth and a fingerprint reader - great stuff!). I came across this piece on a new (to me) Blog that David Fletcher edits. It's part of the Utah family and covers, amongst other things, Voice and Data Networks in Government. David notes that WEP does not go far enough for security and I know that he's right - I guess I wondered (given he notes how much security has slowed down his own initiative) how much we could get done with only that. If the risk is that people ride your bandwidth or steal some of the traffic, then what is the split of applications that you'd allow to run? If you encrypted what was running, what would the new split be? If all the servers were locked down and apps could only be run from known Ipaqs/tablets with known IP addresses, what would the split be then? Is there some set of things that you would just kick off with just WEP, so that people could see the benefit - and then, in the background, work out all the security stuff? David is clearly way ahead of anything that we're doing in the UK that I'm aware of - 100 hotspots on the network already (99 more than I have in my network at home!). And yes, I think government should support public WiFi networks as part of the drive to get the economy wired.
