Patent filed

Finally, I have finished to file my patent regrading PVTD - The Private VLAN enabler.

It is storage how a patent attorney is able to add so many words to a technical document which he has got very limited understanding of its content…

Anyway, I am back to authoring labs. Hope you will enjoy them…


I have just published a virtual appliance with a free 30 hosts license.
