A bit off-topic, but I just read the features list for mosaic (http://groups.google.com/group/alt.hypertext/msg/7fde2f6d4d5...) and was really surprised how close it is to browsers nowadays. The only serious improvements that current firefox has over that mosaic are: tabs, JS and blocking stuff. (I'm not counting stuff that's just a simple improvement - like rendering new html+css, ability to use icons for favourite pages, etc.)

It's a bit sad :(
