Like you said, the GPL is a distribution license, it only applies when
the code is distributed, it does not force you to *publish* the changes
or absolutely _anything_, it forces you to give the changes to the
*recipient* of the modified binaries, which most of the time will be
the same company anyway (a datacenter move for example).

Pico's architecture doesn't seem very ready for embedding, but if
you alex want to go in that direction, i'd suggest LGPL for the
interpreter code, as Guile uses. Or in any way right now, LGPL or BSD
for the standard library, to prevent linking issues that could arise as
Edwin pointed out earlier. I could add too, a BSD implementation of the
PLIO (that i'm coding myself right now)

The BSD doesn't guarantee that either, in fact BSD never guarantees
that the changes will go back.

In that one i agree, the GPL is a huge legal document, and as such so
many people don't read it before talking about it.
