Are multiple installs good friends?

[emanwebdev]

G'Day for you,

Idea/Need:

A different theme/look/install per section of the website

+---- Services : this theme here with these plugins. 1st instance of GS
+
+
+---- Portfolio : another theme with a gallery plugin. 2nd instance of GS
+
+
+---- aso aso... n'th instance of GS. No links between the instances btw.

What's the best solution to achieve that?

How to allow pass-through fancy urls to the 'inner' sections of the site/instances of GS??


Thanks in advance for sharing your knowledge and for your precious time

Best Regards,
Emmanuel

P.S.
After 2 or 3 hours peeking & poking around, THANKS! as
i'm starting to REALLY enjoy GS!!
