i've been fortunate enough to work on sites that are hosted here at work.
none of the machines are jam-packed with sites and most of the sites don't
do gigabits of data transfer each month so it's less of an issue.  however,
i've done sites that sit on virtual servers and they suffer constantly.
they're better if i'm careful how the applications are written, but still a
nightmare under any kind of load.

consider that a custom tag is executed in its own memory space.  one call to
a custom tag in each request isn't going to cause problems.  however, start
calling that custom tag inside a loop of some kind and you're asking for
major problems.  so, using custom tags carelessly could hang the server.
i'm not just hypothesizing, i've seen it happen.

just don't try to interrogate the caller scope like you would a normal
structure -- boo, bad allaire.

just don't try to interrogate the variables scope like you would a normal
structure -- boo, bad allaire.

and the best thing about neo that i've read to date:

<tip type="ColdFusion" author=".jeff">

building an enterprise application and a marketing/sales weenie asks you if
it can be distributed on cd?  if you're using neo you can answer "no
problem" with confidence.
