What is the requirement for the sites, are they going to be completely independent in design, or same site with some specific styling for each page ?
The reason I ask is that if they are going to be similar, you can accomplish this relatively easy using ezwebin (Webinterface) and the setting 'RootNodeDepth', in site.ini [SiteSettings].
>Will I be able to add group sites, based on the same database, each one having its virtualhost ? Yes, but you need one siteaccess pr page.
In that case you should not use the RootNodeDepth setting, since it would require a structur like this:
root
|
-Page 1
|
-Page 2
| -Page 3
Or in words, all sites must be on the same node depth.
So in your case you can use the different siteaccesses override files to assign different pagelayout pr siteaccess, the override in the math siteaccess would look like this:
Keep in mind that you can't use the template_look class to control site look since its not multi site safe. In the pagelayout included in ezwebin, its assigned to the variable $pagedesign.
