VMware just updated three beta programs together, allowing testers access to Workstation 6.0, Player 2.0 and ACE 2.0 release candidates.
All betas share the same build number (42757) and this is quite understandable considering Player is a subset of Workstation and ACE is a superset of it since version 2.0.
While new builds of Workstation 6.0 and ACE 2.0 seem to introduce just integration with each other, Player 2.0 RC shows some surprises introducing experimental support for 2-way Virtual SMP, USB 2.0 support and Shared Folders.
VMware continues to call current ACE 2.0 beta as Enterprise Edition, probably meaning a limited amount of ACE capabilities will be available at no additional cost in Workstation 6.0.
As not enough VMware is offering ACE 2.0 Enterprise Edition for free to VMware Infrastructure 3 customers until April 16.
