> What do you think about Silver Peak virtual WANOP solution ?
No idea. However they aren't a small startup/open source solution like you were originally looking for! Pretty much everyone's solution is written as software that runs on Linux (sometimes BSD). That then gets packaged up on an hardware appliance, suitably tested, marked up and sold.
Consequently not much is needed to make a virtual appliance, although testing is harder as configurations are more diverse. In other words it is likely to be substantially in behaviour to hardware appliances (unless they deliberately exclude things to protect hardware appliance sales).

Thanks for the extensive comments.
