I hit that too.

Would be nice to have the web page indicate status.

I hit that too.  I use gpm as a way to use my slow
eraserhead mouse sometimes and my optical usb mouse other
times under both console and X.

If fact, vncdirect run just fine with /dev/mouse pointing to
/dev/gpmdata with the exception that it left a trail of
little rectangular droppings exactly the size of a cursor.

I don't know which approach is most effective but I would
say this.  It should have

1) a way to switch vnc sessions with a keystroke (preferably
programmable).  Evan and I obviously made the same
assumption about how to do this easily, since I found this
messages looking specifically for this question, which is to
run a directvnc on each console and use ctrl-alt-F1..F6 to
choose a directvnc session.  But for my part, a directvnc
that manages multiple connections would also be just fine.

2) (optional) a way to switch vnc sessions with mouse.  A
meta-pager, if you will.

Actually I was surprised that you allow a cleartext password
on the commandline.  The other vncviewers expect a one-way
encrypted file reference only.  For security, I think (the
details are beyond me).

Thanks for listening.
