I've just spent a couple of days testing Connections out and it does everything I want it to do. I'm using WordPress Multisite with a single site installation and with a few tweaks, using documentation and support from Steven, this plugin will allow me to use a single global directory across all my websites. This implementation will save me a huge amount of time, eliminate a lot of duplication and create powerful content. The more time I spend looking through the shortcodes and filters the more I'm realising that with a bit of creative thinking on the setup and the use of templates, categories, families, shortcodes and filters from a directory perspective you can do exactly what you want to. I'm going to purchase all the templates and extensions because I'm sure at some point I'll find a use for them. I hope this helps.
