is it possible to send a created post to multiple blogs, but to the blogs on completelly independent intallation on new domin? So it is not the multiple site with many blogs under one domain, but independent ones.
It could be security risk to keep the connection between for example 5 blogs with all login and DB informations for each other. And the communication has to be crypted I think.
It's a weird request I get, I've never solved anything similiar.
