Non editable member?

[Sylvain Hellegouarch <sh@xxxxxxxxxx>]

While testing my online APP server, Brendan Taylor told me that my
server was not ensuring the rel="edit" link would exists throughout the
life of the member. This was a bug that I fixed. However that made me
wonder if we could use that behavior to make a member non editable. the
only problem I see with that solution is that it also means the member
is not really one anymore and becomes a plain Atom entry.

Thoughts?
