Of course that it's possible to host multi-site on ONE ip. As Les has
said, it's about SNI enabled web clients and servers. Not all clients
support SNI. As to Apache, there's no need to go with 2.2.12. SNI is
very easy to support with both Centos 4 and Centos 5. There's module
mod_gnutls packed for Centos in one of my repo. Used in production for a
few years now.
