Well I've actually done this before with wiki's. The main thing is you have to make sure the platforms are supported. Importing just any web 2.0 isn't going to work well.
If you buy a gig, make sure its for a platform that is supported by the software, then you can import your URL's you receive and reuse those when you want.
