I think this is absolutely great Halftux.
Very creative a method of approach.
I did try multiple avenues and considered a similar method to yours..
but had to abandon it since my intent was to make a development environment to be so easy a flat-lining rutabaga in palliative care on life support could manage to figure it out and use it....essentially by doing the grunt work for the end-user.
[I'm not calling anyone here a brain-dead rutabaga of course...but I did feel we needed something soooo easy... for the new guard....the new generation of maemoans ...that people brand new to maemo would be able to just jump into development ...and for old guard members...it just makes setup and work smoother and less a pain is all...]
Also my version includes the qtsdk which Peter mentions...
The difference is...my versions are aimed at the n8x0 and n900 [and viable with the 770]
whereas yours takes into consideration Fremantle and Harmattan.

My view is that ...the more diversity and choice in options... the better.
Hard-difficult, easy-simple, large package or small,
Offering many things or even just 1 impossible-to-find-and-utilize function.
The more varied methods of implementation ...the better.
I think it's all great. And I think how and what you've done is very sharp, innovative.
