Exposing Excel as a Webservice

In any case, option #2 sounds like the most theoretically sound. It
sounds like you are using Excel as a database, and your worker thread
as a transaction queue.

Something to consider: do you really need to modify directly a
spreadsheet? Can you not use another format to feed a template
spreadsheet (ie. xml or csv), and then modify that file as a text file
without the overhead of Excel?

Just a thought....
