If you are installing an operating system, how do you have access to a
browser?

Remember that web applications run in a limited sandbox -- they cannot
access the local disk arbitrarily.  You will have to send over an
application to control things on the client side.  You can certainly
download a desktop application, pass the parameters to that application,
and then have it continue just like the current installers, which will
fetch the additional files.  All you are doing is starting the process.

Why do you think one session will affect another session?  There is no
reason on earth why that has to be true.  All you have to do is send
over a "session identifier" during the first contact, then any
additional contact can send back the session identifier.  You can have
several machines doing installations at the same time.  You just have to
remember how far along that particular session got.
