In the 10 year or more that RDS is available in Europe, I have never heard of such abuse. For those of who in the US: RDS not only displays traffic and other information, it also has automatic switch-over to stronger frequencies that carry the same radio station. In Europe, country wide radio stations very popular and the automatic switch over is really helpful when driving distances longer than, say 40 miles.
I assume that the pirates somehow transmit a second signal that overlaps with the frequency of a national radio which causes the redirect. As far as I know, doing this would result in quick reaction to search and shutdown the pirate, though.
My company has developped a PCI DSL card. The PCI DSL card can't be compared to the external box (ADSL in - Ethernet Out): the most popular ADSL chipset (DynaMiTe from Alcatel) has only an ATM output. The external box must add a compilated (and thus, expensive) ATM to Ethernet convertor. On a PCI DSL card, this hardware convertor is not present and ATM cells are delivered to the PC. It is then up to the driver software to extract Ethernet frame out of the ATM cells. (An alternative solution that is also on the market is PPP-over-ATM). Porting the complex drivers from Windows to Linux is a fairly complex undertaking, though I expect that this will be done in the not-so-distant future.
I think what we are experiencing here, is an evolution of the WinModem debate: while it is possible to make a full-hardware standard modem, you cannot avoid a whole bunch of control firmware for more advanced technologies a la ADSL. As a result, every piece of hardware could be classified as a 'WinSomething' because you will need dedicated drivers to get it to work.
The only hope is that Linux will be strong enough to persuade companies to invest in dedicated drivers...
