We are looking for software that will allow users to create a VPN server on their computer at a wireless hotspot. We are looking for something similar to iOpus' iPig VPN software. We do not have a lot of details on this, so suggestions will be more valuable than a low bid.
Description of iPig:
Set up a VPN server in less than 1 minute. Free client software. iPig creates a secure "tunnel" that protects your inbound and outbound communications (Email, Web, IM, VOIP, calls, FTP, etc.) at any Wi-Fi hotspot or wired network. iPig works with any kind of Internet connection (Wifi, WLAN, wired ethernet). iPIG shields your data from even the most sophisticated methods of online spying and snooping like the "Evil twin attacks". The PRO Edition allows an unlimited number of users (only limited by system resources).
