Do you mean "dynamic DNS" or "name-based virtual hosts"?
In the former case, anything is possible as long as DNS is accurate and
up-to-date.
In the latter case, you can only have one SSL cert per IP address by the
nature of the protocol, and other protocols (like ftp) that connect to a
the IP dereferenced by the hostname, but don't include the hostname as
part of the connection, are limited to a single host-per-IP. There are
other protocols with that limitation, but SSL and FTP are the "biggies".
Anything run out of inetd will have similar problems. (f.ex. you can't
have multiple "telnet" hosts on a single IP address.)
