Hmm, most of the world has mobile phones these days (all the ones in my DB
will be for example) The percentage of homes in the UK for example with no
telephone is increasing quite considerably.
I concede the point though, it may be too far currently (we have the same
problem with mbox though, many people share mbox's) Maybe we can have
foaf:mobileTelNo which is an IFP?

I'm not giving people URI's, and it does nothing to solve the smushing the
issue, of how to smush my group with the rest of the foaf world.
