Nice to hear that things are moving forward.

I would like to make one BIG suggestion. Build a new generation Lush on top of Qt.

There are many advantages to this, of which I am sure at least Leon is aware from
his work on DjView, for instance.

Qt can serve as a platform, rather than just as add on functionality. Lush will then
be automatically cross-platform and be able to serve up native GUIs and services
(DBus on Linux, Cocoa on OS X (coming in Qt4.5), WebKit, ActiveX on Windows, etc.).

A number of other languages already have Qt support (Java[QtJambi], Python[PyQt], Ruby
[QtRuby]). Providing Qt would not only put Lush on a par with those other languages,
but put it above if implemented in the fashion of a platform that Lush works over.

There could be separate versions via a configure switch that will either build a full
Qt enabled version or a lighter weight, more traditional, version.

I have already planned to use Qt for my Java/Lush version (via QtJambi), which I started
months ago working initially by porting from Leon's minilisp code in the dejavulibre library.

On top of this, I would also like to suggest that the GNU Toolchain be dropped in favor
CMake (which has many advanced options, supports Qt projects, and makes projects simpler
to maintain).

Cheers,

Raymond
