Hi Guys,

Sorry I sent that last e-mail before reading the full list.

If Bryan needs Dansguardian built in that's good enough for me. I take 
back what I said about it not being critical.

Let's put it on the roadmap for 0.6 and see if we can make it happen in 
time for Nepal to deploy it.


What is the delivery date of a tested and working version which will 
meet your time frame? I want to make sure we give it you with enough 
lead time so you can test it before you put it in production.

Yeah, that's one of my concerns. I looked a little bit at DG
documentation a few days ago, as I was fighting with Squid's memory
usage, to understand how resource intensive it is, and how it works.
And in the back of my mind the question was - is this the right tool?

When you mention it blocks most content, I'm less than thrilled. A
filter that is too blunt will actually backfire -- will be too easy to
false-match and also easy to workaround. Users will learn something
but perhaps not what we want. A smarter filter, one that does not give
all/most users an incentive to find workarounds, is a much healthier
solution. But I'll get deep into it later, more likely in the 0.6

Now that you mention you're using it in a real life setup, what does
top tell you about its memory usage?

Noble causes indeed!
