The site qyoto.org is now defunct, but we are certainly very actively
maintaining the bindings.

Yes, we might change the Qyoto license to LGPL and/or we might add the
option of a paid-for commercial license that you could use either with the
LGPL version of Qt or the commercial version. However, the current
maintainers of Qyoto (Arno Rehn and myself) would need to get permission
from past developers of the code in order to do that.

Yes, Qt is a really, really good toolkit and it is getting better all the
time in performance and functionality.

Qyoto uses the 'Smoke' library which is a language independent,
automatically generated dynamic runtime used by multiple projects (Ruby, C#,
PHP and Perl bindings for Qt). Someone has sent patches to the
kde-bindings at kde.org mailing list for making Qyoto compatible with
Microsoft's .NET with relatively minor changes. We will add them when we've
got time. I'll cc this mail to the kde-bindings at kde.org mailing list so that
other people can make comments about your questions.
