Generally, multi-domain life seems to exist indeed in a rather limited way -- mostly regionally using ENUM-like technologies to find target domain. I'm not 100% sure yet why is that, supposedly the economy of interconnection via PSTN is favorable.
wrt to security it seems that attackers are apparently not worried about what we think about multi-domain stuff or not. see the reports on the recent incidents in Germany I posted before. The interesting part I find here is we can set up a barrier which does not take inventing new protocols. -jiri > Thanks Dean.
