The problem is that I can't show the real work I do, since that's a secret.

Fortunately, I can show a tip of the iceberg of what I can do.

Here is a quick picture that a draw up in several minutes.

Here you see a networking topology model (primitive diagram - without
IPs), that could be simulated inside single PC (provided the PC is
powerful enough of course - actually - Servers can handle the task).

Every link on this topology needs to have host interface connection,
because I tend to run multiple emulators at once, and interconnecting
between them... Say Dynamips/VMware and VirtualPC - all of them can be
interconnected together.

VirtualBox cannot participate in such a network, because I cannot join
a VBox VM into this topology, because it uses Windows bridging which
is limited to only one bridge.
I need a solution, that is scalable enough to handle hundreds of
connections simulataneously.

In other words, I use Host-Networking to communicate between different
emulators, instead of between external world and an internal one.
While some emulators provide "internal" networking feature, you cannot
use it to communicate across different emulators.
Creating a virtual NIC is the only option here. (by way of MS loopback
or by way of TAP, doesn't matter)

Note that some Servers have dozens of physical connections. Think if
you have 5 PCI slots, and each has a Quad-Port adapter, that totals to
20 !

The solution must be scalable enough to support those extremes.
