"WinTel is our popular Cocoa graphical user interface
to control the powerful underlying open-source "Bochs"
x86 emulation software (Bochs is pronounced as Box)."
Though, one might need to test that program first, as
their introduction says that it is "just" an user
interface to control Bochs (=configuration interface).
In this case, it shouldn't be mentioned there, as $25
and more is way too much for a simple configuration
However, their FAQs state, that the "performance is
very similar to VirtualPC". So either it is a lie, or
VirtualPC is very slow on the Mac, or they improved
Bochs themselves (not sure if it is legal in terms of
the LGPL). If it is all legal and it is fast for
real/faster than Bochs on the Mac, it should be
mentioned at the related projects site.
