You are comparing apples, oranges, beef and chicken.
NetObjects is a completely different solution, and they never brought their
"team" solution to the mac.
GoLive is a great page design tool, and their team tool is still coming
along just fine. Being owned by Adobe and having their stuff brought over
to windows is a good thing.
Macromedia Dreamweaver (not mentioned, but should be) is another GREAT page
layout tool.
GoLive and Macromedia dreamweaver both work great with WO.
But... You really don't need WO unless you plan on doing a heck of a lot
more than this. I would stay with perl scripts -- its cheap and simple.
Way better than WO pricing, unless you are an educational institution.
Seriously, you don't need an application server at all from what you have
written. Get the GoLive publishing system when it comes out (real soon now
they keep saying), or just stay with the simple/cheap system. You won't
have any scalability issues, you won't need to keep a programming staff
nearby, you will sleep better at night.
Use the best tool for the job. In this case, webobjects is like a
hydraulic jackhammer to drive a nail.
