c) is the way to go.  A smooth upgrade path is everything.

I think it is worth pursuing.  POST results in history lists are a
major problem for both browser authors and forms+CGI programmers, and
c) is a simple 90% solution which can be deployed quickly.

In the long term we need 

 1) real transaction support
 2) a standard for history list behavior

to solve all problems one encounters when trying to make a robust
forms based user interface.  Differences in history list
implementations continue to be a major problem for forms+CGI
