So I'll be using Joomla for a few sites, and WordPress for another few. How is this done? Do you do a complete install, from scratch, of Joomla for each Joomla domain and of WP for each WP domain? If so, can this be done with Fantastico? When it comes to adding plugins and extensions and such for both types of sites, do you have to do them separately for every Joomla and WP install/site?
How resource intensive would this scenario be on a shared server hosting plan like those offered by BlueHost or Hostgator? Each Joomla install uses its own SQL database (I think), and I'm not sure what WP uses. I understand that Hostgator has a limit of 100000 "inodes" per account, so I don't know if 5 to 10 fairly small blog and basic content sites using J and WP would run into problems with this limit or cause the hosting company to shut them down for using too many resources on the shared server. I don't expect any of these sites will be getting a ton of traffic (at least not at first), so I don't want to get a dedicated server with its much higher costs.
