My guess would be customise a skin. If you look at any skin folder they have a file posts.main.php
I would guess you could put some custom code in here and it could point to another db.

Also if you look at _blog_main.inc.php it has a section

$disp_handlers = array(
					'404'            => '404_not_found.main.php',
					'arcdir'         => 'arcdir.main.php',
					'catdir'         => 'catdir.main.php',
					'comments'       => 'comments.main.php',
					'feedback-popup' => 'feedback_popup.main.php',
					'mediaidx'       => 'mediaidx.main.php',
					'msgform'        => 'msgform.main.php',
					'page'           => 'page.main.php',
					'posts'          => 'posts.main.php',
					'profile'        => 'profile.main.php',
					'single'         => 'single.main.php',
					'subs'           => 'subs.main.php',
					// All others will default to index.main.php
				);

This looks like it is the types of page or part of page. I would imaging you would need to customise one of these files.... or maybe add to this list. I am following this topic as I would be interested to know.

You can easily [url=http://forums.b2evolution.net//viewtopic.php?t=14046]create custom pages[/url] and use PHP to pull the data from external database (or table)

ok these suggestions definitely point me in the right direction. My knowledge of php is pretty basic but I'll take a look and try a few things.

I took a look at the link to the create custom pages and doesnt look to tough but I really dont know what info should be replaced. My coding level is pretty basic with mostly cut and paste.

Thanks, I'll keep exploring and see if I can come up with something.
