ShadowPlan desktop for FreeBSD

Dear Jeff,

I am a registered user of ShadowPlan for Palm, Windows and Linux. I was
reading through the manual earlier and I noticed it says: "Shadow Plan
for Unix is currently available for Linux, though please let us know if
you'd like a FreeBSD or other build." I find that the Linux desktop
works satisfactorily under FreeBSD (using Linux emulation) but as I now
use only FreeBSD I wonder how much effort would be involved in building
a native FreeBSD version? I would be happy to pay for another licence,
though at the prices you charge I realise that is not much of an
incentive. I think I am asking this simply because I know how easily
overlooked FreeBSD is by the Linux crowd (please, that is not meant to
be flamebait). 

Best, Tony
