OMG yes on wildcard certs! My company has multiple domains and uses subdomains for every affiliate and we have thousands of affiliates. One *.example.com cert per domain and we're good to go. Now if only we could get IIS to support multi-domain wildcard certs so we could get all of our domains and subdomains under one master cert I'd be in heaven! (SNI doesn't work for us b/c ~12% of our traffic still uses IE7 or earlier).
So why not buy one now? I get the excitement about simple certification process, free access and refresh, etc. But if you have thousands of affiliates, current wildcard cert providers should offer a pretty good solution. Is anything missing there? I mean, if we ignore the idea why LE is good in general, $100 / year is nothing if you actually need a wildcard.
Oh we absolutely do just buy them now through RapidSSL. It's all of those other reasons I wish LE supported them. I wouldn't mind paying LE for them, I want an API for requesting them, a simpler certification process, and easier refreshes.
