The problem is both NetBSD kernel and Xorg server are
quite larger and require more CPU power than 1990's binaries.
IIRC NetBSD/sun3 1.1 kernel was only ~700KB, but in 6.1 it's
larger than 2MB.
IIRC there is a wsfb driver for mplayer on x86, but I'm not sure
how much CPU power is required.

Yeah, "demostration with motion" is also important at events..

The problem is the load of authentication via SSL.
Posting a tweet takes ~10 minutes on 68030 25MHz LUNA
via pkgsrc/net/ruby-tw. (though I have not tried it recently)

Most of my recent projects (Atari SMC_TT, hp300 wscons,
resurrection of luna68k and LUNA-II support, x86 liveimage, and
mlterm-fb etc) were driven by the events like Open Source Conference
and Kansai Open Source, as seen in the event page :-)
