good to hear ...

 The only thing missing for me is a way to automatically log users
 in their right vserver. It could be having a SSH server in each
 guest listening on different ports, but it means every user have to
 know his own port and every vserver must be running all the time.
 I'd prefer having only one SSH server on the host, listening on
 standard port, and something launching the appropriate vserver after
 successfull authentication of users, a bit like does the pam-chroot
 module for...chroot.

there is a trampoline script which can do this:
http://vserver.13thfloor.at/Stuff/SCRIPT/trampoline.sh

 Does such a tool already exists or is planned?

as specific tool, no

 Is writing a 'pam-vserver' module a good thing?

maybe, at least it sounds interesting ...

 Could someone drive me, at least for beginning, to write my tool. I'm
 running Debian Etch and there's no '*vserver-dev' package. I'm a bit
 confused with which includes are needed and where to find them.

well, no idea about the debian packages, on mandrake
the package is called util-vserver-devel, and it
basically provides the lib (libvserver.a/so) and a
single include file (/usr/include/vserver.h)

you might want to have a look at the vcmd source too,
although that is a hack tool for testing, but it is
able to generate any kernel syscall command used for
Linux-VServer, and it is supposed to work on all
platforms ...

HTH,
