It would be really great, because OpenBSD has a lot of built-in security 
features, for example W^X.

I think one of the biggest problems preventing usage of Xen in some 
environments is lack of possibilities to highly secure guest systems -
for example great PaX (most important part of grsecurity).
We all know, that standard linux is totally defenceless against so 
popular buffer overflows exploitation, or format string bugs ...
