I'm not sure how to tell you to do a web based install. However, there is a product called WinBatch that will allow you to create a silent install of Oracle Client among other things. It is a very powerfull scripting language. I am using it to create a nearly silent upgrade of Oracle 7.3.4, 8.0, 8i to Oracle 8.1.7. This might suit your needs. It also has web plugins. I'm not sure what they can do since I haven't used them.
