in a project of the German computer magazine c’t, they developed a debian/etch+XEN based distribution for which a debian package is available that contains an installed ClarcConnect in a XEN DomU.
Maybe it’s interesting to look after it. The other DomU is an Endian based firewall. I guess a vdr DomU will follow and I will install mt-dappd inside of it. 8)
