Re: Certificates are not for encryption only.
When news of the initiative broke last November, I asked EFF whether they would be working with CA-Cert who have been dealing with individual and organizational identity verification issues. EFF's Peter Eckersley's response was:
"We aren't working with CA-CERT, but we're partnering with and receiving advice from people who've run a number of other widely-used CAs.
Securely encrypting the Web is sufficiently important that we will be able to raise enough donations and membership contributions to run ISRG with a proper budget."
That's a pity, as the initiative's industry muscle could have ensured a cross signing of the root of a long standing free community CA infrastructure with distributed procedures and processes behind it.
