Do anyone knows, how I can get my two network adapters in the same computer
to co-operate, so one of the parts receive at 100Mbit and the other transmit
data at 100Mbit on the network. So I can triple the speed of pending. Can it
be done?

If you are using a switch, or other connection capable of FULL duplex, then
a single card can receive and transmit at 100mbs at the same time. (Cheap
cards might not really be able to keep up, but a quality one can, minus
overhead, etc..) The maximum throughput will not be more than 100mbs each
way. There is no way to triple (that is 3 times) what a single card can do
unless you have three data paths.

Bridging amplifiers will give triple output when done correctly, but
unless you write a new spiffy network protocol, you can't do it with
dual network lines. Not to say it can't be done, but I haven't heard of
it being done yet.

If cars had advanced at the same rate as Micr0$oft technology, they'd be
flying by now.
But who wants a car that crashes 8 times a day?

Comparing apples and oranges. Bridging amplifiers combine the analog
outputs of amplifiers, adding the voltages. Doubling the voltage into the
same load gives 4 times the power (ohms and watts law). So in theory, a
bridged amp can give 4 times the power, but triple is the practical limit.

Now on to multiple network lines for more bandwidth. Used by every ISP in
the world with more than one T1 connection. Look in Linux documentation on
ethernet channel bonding. Bonding adds the bandwidth of each channel. 2
100mbs channels gives 200mbs.
http://sourceforge.net/projects/bonding
is one of the projects for Linux.
also see http://www.linktionary.com/l/link_aggregation.html There are
multiple ways of implementing and managing this.
