[Typo3] Multiple sites and existing applications on Typo3

[Saranyu Lavanyakul]

Hi all,

I am evaluating a few opensource CMSes that would fit our requirements. 
We run multiple sites with many shared information and existing 
application using JSP/ASP.

Will single Typo3 instance be able to manage multiple sites using static 
export? Will it be able to shared text information on many sites using 
different look and feel?
Would you know any CMS that would fit the requirements like this.

Thanks a lot.
