[wp-hackers] creating blogs across several installs

[Potkanski, Jason]

There is not an IP requirement on the multi-site plugin. IP addresses/interfaces are handled transparently to the Wordpress application by Apache. You can keep the multiple IP addresses per site and still use multi-site.

Unless you have a per IP licensing requirement, SSL certificates or something strange, IP addresses are not necessary per site. Multiple sites per IP address has no bearing on SEO.

The other Idea in the back of my head is to create a plugin that automatically creates the blogs on the other 4 domains and installs MySQL triggers to automatically update the other 4 blog tables. You would have to develop tricky update triggers for wp_options.

Jason,

The multi-site plugin is something I've looked before but it doesn't
seem suitable because it requires that all the sites point to the same
IP address.

As I mentioned before I have 5 different IP addresses with installs
and I need to keep that for SEO purposes.

Any other ideas?

Thanks,
Nuno
