Do you actually own hundreds of personal websites? (And you could still desync them, anyway.) Or is this a use case where wildcards would be useful. I sort of disagree with LE's decision to not care about wildcards for now, though I understand that it's simpler, at least while it's in beta.
That's per IP, you're also limited to 5 requests per domain name per week. In my case, I have a bunch of subdomains for various stuff that all counts against the limit for the main website. I suppose I ought to combine the CSRs, but implementing that makes it a bit more complex than just automatically requesting a certificate per nginx vhost.
Still, with enough automation, you can request 5 per week in a cronjob, which will let you get at least 40-something websites, even with the recommended 60-day renewal cycle. :-P
> Certificates/Domain you could run into through repeated re-issuance. This limit measures certificates issued for a given combination of Public Suffix + Domain (a "registered domain"). This is limited to 5 certificates per domain per week.
If SAN certificates make sense for your setup (i.e. all used on the same server or for the same service), you can have up to 100 (sub)domains on one certificate, or basically 500 per week.
I did a bunch of requests starting with one subdomain, then a second, adding SANs multiple times, setting a cron to do one request a month and testing it, then adding yet one more SAN to the list.
