Would that mean supplying names of key/certificate files to OpenSSL, or
are you thinking of sending parsed keys/certs (like
SSL_CTX_use_PrivateKey() etc. does right now)?

Dealing with encrypted keys might become more tricky, depending on how
the API for this would look like (currently, mod_ssl remembers the
unencrypted keys in a separate table, so that they can survive a
reload).

This would certainly help. Things which come to mind: host name mismatch
(i.e., cert does not include DNS name for ServerName/ServerAlias),
private-vs.-public-key mismatch, missing chain.
