The question is, how different do you want the "towns" to look.
Looking over your post, it isn't really clear how much segregation you want between the two "towns". If you're wanting a completely separate look (theme) and adverts for each town, just run 2 installs of XOOPS. If you're wanting to share information between the sites, then it gets complicated.
If you want to share information between the 2 "towns", there are 2 "stable" ways to do this that I know of.
1. Use MySQL 5 and share the tables you want to share between 2 installations of XOOPS
2. Install modules that have categories ("towns") and separate the content of each town into the the categories ("towns").
Quite honestly, it would help if you provided a little more detail about what you are trying to accomplish.
HTH.
