I think this is a good idea - things like the line mode browser
appear to be being left behind in the dust by the Mosaic crew.

How about something like 'native WAIS support'?

Just want to point out that my w3 browser for emacs would be
considered a 'Level 2'. It has support for HTML, HTML+ (mostly), the
ALT tag in IMG, and HTTP/1.0. :) It also supports most of the <INPUT>
tags for FORMS (no pulldown menus or password entry fields yet - but
its being worked on) No native WAIS support yet though. It should be
coming out of beta soon (end of the month hopefully)
