Setup both devices at each location, remove existing antennas, connect antenna cables and your directional antennas. Point the antennas at each other (toward each house). Login to the ipaddress of your access linksys point/router. Find the firmare upload page. Then Google "Linksys Tomatoe firmware" download and follow instructions to install it.
You will eventually replace the firmware, log back into the linksys device and setup the access points as multipoint/bridge functionality and modify the IP addresses to something like 192.168.64.x (x = any number 1-254, but seperate for each device.) You should then be able to see the other access point. Your ISP can do the DHCP settings for both computers. You should be able to chat, video, message, play games, transfer files, remote desktop, vnc or what you want to do online or offline cause you essentially have a wireless LAN. So don't forget to setup some security. The tomato or linksys documentation should explain some options.
The materials could be acquired all for under $100.00. I'm thinking the cables and antennas might be higher than the actual device themselves.
Hope this helps some more,
