Help with choice of suitable Architecture

[Rob Cowie]

Thanks for the comments.

I kind of get the impression that CGI is the way to go for this
application, and that I should forget about adding client-side
scripting based functionality for the sake of accessibility - which I
understand and kind of agree with.

I'll look into the problem of concurrent access to an XML file. I may
get back to the group about this!

Cheers
