introduction about the speaker

legal disclaimer

free software and it's role in computing
	increased use
		not only server market
		not only desktop market
		but _large_ quantities in the embedded market
			router / gateway / firewall
			wireless acces points / bridges
			network attached storagee

free software development model
	distributed developers throughout the world
	contributions from anyone with required skills
	as a result, distributed copyright in many projects

free software and it's licenses
	free software != public domain
	free as in freedom, not as in beer
	significant part covered by gpl license

gpl revisited
	terminology
	revisiting
	complete source code
	derivative works
	collective works
	non-public modifications

gpl violations
	when do i violate the license
	what do i risk

past (until 2003) gpl enforcement
	most of it quietly
	in many cases handled by the FSF

the linksys case

typical enforcement timeline

success so far


summary / what we've learnt
	a lot of companies don't take free software licenses seriously
		even companies with large legal deprartments have problems
		why is that? lack of information? financial risk not hard enough?
		it's not different to any other software license of 3rd party components

	the FUD spread by certain corporations 'can the gpl be enforced' has vanished

problems of gpl enforcmeent
	distributed copyright is a safeguard, but can make enforcement difficult
	the need to do reverse engineering to proof the violation
	infringing companies obfuscating or encrypting free software
	legally difficult to claim your rights as customer of gpl infringing product
	damages claims can be difficult due to distribution problem

gpl enforcment future
	I just wanted to set some examples
	so many cases, further enforcement has to be done by organization
