Then a user could go to mobile.livejournal.com/vcards and get an aggregate *.vcf file of all their friends' vCard data, optionally complete with userpics (since you can put those in vcf files).
But my phone (Treo 650) doesn't support vCard 2.1's UID property, which is supposed to prevent collisions on import/merge, so every time I download my aggregate vcf file I get duplicate records of anything I had from the previous import....
Useless!
