[linux-lvm] clustered lvm without clvmd

I have a lvm VG on top of a iscsi lun, and want to share that on
multiple hosts in order to run kvm virtual machines on logical volumes.
I recently noticed that xen-server also do this, but they do not run clvmd. Can someone explain how that could work?
I also detected that I can protect LVs by using 'tags'. That way I can
make sure that LVs are only activated by one host?
It is also no problem to restrict VG write access to one host (master).
The only problem I see is how to propagate metadata changes to the other
nodes. How do I make sure that metadata is written back to the iscsi storage? And is it enough to simple issue a 'vgsvan' on all nodes? Or is
that a bad idea?
Psssst! Schon vom neuen GMX MultiMessenger gehört? Der kann`s mit allen: http://www.gmx.net/de/go/multimessenger01
