DES isnt an issue. Dont include the DES support in the IPsec code. Make
it use a clean module interface to transforms [Ted Tso hammered much of 
this out nicely in Germany last year].

I think we have more DES implementations in Europe than in the US. I
also like the idea of the config saying something like

Are you in france or russia	(CONFIG_SEC_ILLEGAL)  Y
*
*	 Skipping security options
*
Are you in the USA		(CONFIG_LUNATIC_PATENTS) Y
*
*	Skipping compression options
*
