Well it sounds like most of your design goals are pointing you towards the web interface. These same goals are what made me choose web even though I knew that I'd have to make some sacrifices on the interface. You'll be able to do it fine on the web, just be prepared to be flexible with the interface and learn to accept/work around the web's inherent limitations. Some thoughts:

May be I will have to fight with Javascript more. > Yes, much more. But a book I found helpful was 'DHTML and CSS for the WWW'. It has helpful examples of various menus and widgets that can be accomplished on the web to make an interface richer. And with that, I think we've officially left the topicality of a mod_perl list. :-) Enjoy, Fran
