Thanks to all who responded to my previous mail, it seems that others had
similar ideas to increase the transmission speed for visual-CW.

For those who also appreciate the 'therapeutic' value of visual-CW and are
not interested in speeding up things there is the possibility to increase
the 'dot-length' by a certain factor (+/- 3). This will ensure that the
duration of the QSO will not be too short and has the advantage that you
can make the QSO with less power or cover a bigger distance with the same
power.
Yes, that's a good point. The length of the dot is the limitting factor in
signal to noise calculations. I often can copy dashes much more
easily than dots, partly because the averaging can be done over a
longer period, and partly because dashes are less easily destroyed
by impulse noise such as QRN (and there's lots of that at LF).
