We've actually evaluated it, are actually using it, and was one of the ones
who described it as being a `pig' to Gary at LISA.

For a small-medium size site, the scaling issues arent all that severe.
However, once you expand to something like the size of Worldnet or Earthlink's
user base, things get really unwieldly, really fast (extrapolations based on
my own experiences).

Granted, my observations are based on Netscape's implementation on a
non-FreeBSD platform, but from what I've seen, the conclusions do extend to
the general case.
