Digital BW, The Print

I have downloaded OPM (from bowhaus.com) and started to try it,
with a feeling of great optimism that it is the silver bullet
that will yeild great B&W prints on my Epson 2200.  I've got a
few simple questions.

(1) It appears to work only if the printer is USB connected.
Will this change soon (to support FireWire connections) ?
(No biggy, just gotta get a USB cable for the printer and a USB
hub since I'm running out).

(2) There seems to be no way to switch between landscape and
protrait orientations of the image on the paper.  It appears one
must rotate a landscape-mode image 90-degrees in one's photoeditor
and save it out before opening in OPM.  Is this rigth ?

(3) When using the up/down arrows for "scale", if you push the scale 
UP to where the image is too big for the page, the arrows seem to
freeze in this weird mode where it toggles between two scales and
you can't get it to go back down below 100% (ok, this is more a
bug report than a question).

(4) The download only had 2 profiles for the 2200; "warm" and "cold"
for EAM/EEM paper.  How soon will add'l profiles be available
(especially for the inksets everyone seems to think MIS will
be supplying soon) ?

Thanks, John
