My particular situation with Ecademy is probably a special case.
- Every user has a flag defaulting to off for email address exposure.
- I always put in the SHA1 hash both for the primary person and for 
their friends
- I put in the email address for the primary *if* they have flagged it 
as OK
- I put in the email address for each friend *if* each friend has 
flagged it as OK.
- Users have the ability to hide their directory detail completely. I 
respect that both for their record and for the friends entries.

I can do this because I'm working from a common dataset. If I was 
building the RDF file by hand from a personal database, I agree with 
Bill that I would only put in SHA1 hashes for the friends.
