This is a bit of an assumption, but if you guys are using WiFi provided through the university that your veterinary school is a part of, odds are it's pretty damn secure. It's not like using the internet at the local Starbucks where they just have a linksys in the back room or something like that. University networks are pretty well fortified.
If it's not a university network, I still hope it's better than the connection at Starbucks, especially with all that patient info flying around.
