I agree with you here...

That's all good, but the main issue IMHO is how do we guarantee that a
script in the chosen language will work on all platforms ? Do we package
the language on platforms that are not guaranteed to have it (full
Python distro in setup? Yuck!)

Integrating xsu in the main code isn't too big of a task, actually. This
is something we could do, although it can be a bit tricky (and xsu is
not working perfectly as is either).

Maybe you should consider Loki's approach were basically only binary
updates and demos are available online (never the full game). Then you
can control the release of the full game as you see fit.

I'm reluctant to change the current loki_update mechanism now - but am
open to suggestions to improve it ;)
