You didn't say where you were going...
If it's to Camp Julien in Kabul, there's a fairly large internet cafe. There were no webcams when I was there, and no scope for plugging your own in...
However, given your timings, you could be bound for Kandahar. If that's the case, you might have access on a very periodic basis to the US systems at the airfield as the Canadian PRT camp is being set up, but that's certainly no guarantee. Expect Kandahar to be much more austere than Kabul.
