From my little experience. I'm prety sure you can achieve the showing whatever pages you want with an initial redirect index file.
redirect url1 to /modules/tinycontent/
redirect url2 to /modules/news/
But if you want to use the urls seperately, whereas it doesn't redirect to 1 url only, then the multisite hack would work quite well for you. Just requires more admining of the site.
Depends on the level of seperation you need with each site.
Cheers.
PS. Of course I'm still a n00b at this.
