I do something related in the new "net" version at www.reactorlab.net.
The approach is described at http://reactorlab.net/intro/tools.htm (link
"Building a "Rich Client" or "Internet App" in Revolution).

Version info is kept in text files on the server and client, rather than
using a script to get file info automatically.  Disadvantage is that you
have to hand-edit list on server when a new stack is posted, advantage is
that you can keep drafts or backup stacks in the directories and not have
them presented to client.
