VPNs barred in court

Note that will it not always be possible to access a virtual private network when using wifi in a public space. The admin of the network may have it configured to bar VPN protocols. This came up for me today in the Minnesota state district court in the Hennepin County Government Building in downtown Minneapolis. The speed of the wifi network in a courtroom was great (more than 50 mbs per second for uploads and downloads), but it would not allow me to connect to my firm's network via VMWare. I got around the problem by getting online with a MIFI device, which connects to the web using a cellular network.
