Yes. The init shown in the vserver is the real init. It is show for cosmetic
reason, mainly to please utility like pstree and friends (so they find the
common parent).
vserver do not have a real init. The inittab is not used to start services. The
only ways to start service is using sysv init script and inetd/xinetd network
services.
An init replacement would be needed for the vservers. I wonder if the standard
/sbin/init would do, with a stripped down /etc/inittab.

A vserver is limited (by default) to one IP, specified in the vserver configuration
file /etc/vservers/vservername.conf. By default, this file contains 1.2.3.4. change
it to 192.168.100.255 and this will work.
Is this a broadcast address ?
Is this the proper way to receive broadcast messages ? Anyone knows anything
on this ?

There is no need for a /boot directory in the vserver because it does not
boot the kernel itself. Create an empty one I guess.
I was not aware of any application needing information from /boot. Should
we provide some dummy stuff there ?
