The FAQ on Express Licensing has been updated and can be found at:
http://wanos.co/wan-optimization/faqs/#express-faq The Express FAQ and the products page should be referred to for the latest info on Express.
Some additional info on the current state of Express:
Express limits and features may change from release to release, so its best to have a look at the
products page.
Express does not include professional support.
Express does not have a guaranteed upgrade path. Put another way, features available in Express may change with an upgrade.
Mixing Express with Plus is not recommended: Future Plus upgrades may have features that are not compatible with Express.
Due to the complexities of mixing Express and Plus, it voids professional support e.g. Companies that have a Plus at a hub site and Express at the remote sites.
Ad Hoc support at an hourly rate has been introduced.
