Looks very straightforward, sane, and flexible - I like it.
Not sure the 'right' way to handle TCP wrappers in this case - should
tcpd checks be delayed until it is determined that sni was or wasn't
used and then check against the actual [name] e.g. virtual vs
sni1? Or should there be two tcpd checks, e.g. check virtual
on accept, and then sni2 iff it turns out that's the cert they're
I'd suggest the former method - it would allow you to have more
open access for the sni services. In the latter method you'd need
to have the virtual service's permissions a union (or greater)
of the sni services.
