Does this help with security?  That is, does it help protect me from
attacks from across the Internet?  Or does it simply help applications
from interfering with one-another?

I'm currently running sed 2.05-19.  I'm running a full hamm installation
and I just updated this morning (Dec 1st).  Would you suppose my problem
is therefore fixed?  Would deinstalling and re-installing efence help at
all?  What pitfalls do I open myself up to if I remove efence?

Hope that's not too many questions...:)

Thanks loads,
matty
