I'm not sure if I'm interpreting you correctly, but you seem to want:

http://server.com/people/<something>

...to pass the string "<something>" as a parameter to a ZPT, while:

http://server.com/people/<something>/<somethingelse>

...is served normally?

If you do it exactly this way, it is going to cause you pain the moment 
you try to manage /people, since your '/people/manage_main' will get 
handed off to dispatch.

I recommend adding a way to distinguish these special requests, such as 
a prefix for the path element. In that case, you want a Script inside 
/people set as the Access Rule for that Folder:

req = container.REQUEST
trstack = req['TraversalRequestNameStack']
if len(trstack) == 1 and trstack[0][0] == '*':
     # There's only one path element left to traverse,
     # and it starts with a '*' prefix
     req.set('dispatch_arg', trstack.pop()[1:])
     trstack.append('dispatch')

Then, in your ZPT, use "request/dispatch_arg" to access the parameter.
