Hello,
I am the project leader of GNS3, an open-source program that you can use to create virtual networks based on Dynamips, Qemu and VirtualBox.
I don't know if this is the right place but I would like to know if VMware could implement UDP tunnel networking in some of their products (most important being VMware workstation and player). What is UDP tunnel networking? Well this is explained in this document.
For an actual implementation, you can check out VirtualBox's one.
I really think this would not be complicated at all to have this integrated and also controllable from an API. It would be very useful for all kind of applications and would allow me to add VMware support into GNS3 too.
Let me know if I could direct my request to someone or please leave your comments
Cheers,
