I think that the dialogue you captured is the "seam" people are
talking about :-)

In any case, I think this discussion has missed that what Bryan is
requesting is *much* saner from a security POV than downloading
putty.exe (which is as bad as it gets). Bryan wants to be able to
provide links that start existing activities on the XO - a
document-triggered launch (using JEBs) is good enough, and I think it
can be deemed reasonably safe. We trust (and confine) the activities
on the box.

So I don't think there's a major problem here.
