yep, ftp://elba.math.uni-potsdam.de/pub/NetBSD/sparc/

some people got it running, but my IPX is somewhat slow for Netscape 3 or better.

yep, I have to offer: Afterstep, fvwm2, fvwm95, mlvwm (Macintosh lookalike) qvwm ( even more win95 like than fvwm95 ), amiwm ( Amiga look ) ...
oops, sorry, just had a look onto my ftp directory, only afterstep and mlvwm are currently available as binaries. if you take Mosaic remember to fetch lesstif too.
