• Both will need to be on the same version of AC so either she upgrades or you install the previous version (which should not be a problem).
• You don't need a dedicated server for TW though it helps but if you are working remotely you will need a Static IP Address to connect between both. Don't know about RVT coworking but I have heard that it is way more complicated than AC's.
