I can understand your concerns and yet I can also see Koen's point of
view too. I don't think Koen would object to you creating an SDK to use
internally, I just don't think we want see one being made public at this
time for the reasons mentioned.

Ultimately, the plan is to have packaged staging. Each developer would
then install OE but instead of building from scratch, it would populate
staging using packages from some repository if packages were available.
Angstrom would provide such a feed. This has been partially implemented
but isn't complete yet and needs further development work. It will be
the way OE addresses this problem in the long run.

Another solution if you have a set of identical build environments on
the users machines is to ship a half built copy of OE. Developers would
then be able to build their apps within that. The build would have to be
installed in the same place on each machine but that might not be a
problem.

A third solution is to run OE under some kind of virtual environment
thereby ensuring the identical build environment mentioned above.

OE has many ways of being used, in some ways, too many but that power is
also one of its biggest features! :)

I hope the above comments help,

Cheers,
