Apart from minor details I agree with this comment anyway.

What do you mean "disagree" (this is a case of fact rather than opinion
--- i might be wrong but it's pointless to "disagree").  

The price in 1997 for a Local Director or PiX (h/w was same at that
time) was about $40K.  Either it's still at that level or not.  IIRC,
the Pix, at least, has come down quite a bit ... but there has been more
competition in firewalls than in load balancers so you may be right.

What "myths"?  Whether you call it h/w or s/w is semantics.

The LD and PiX used OTS h/w (Ppro, PC mobo) in 1997 (i opened one).  The
interesting piece was a proprietary daughter board but AFAIK, that ran
Cisco's own O/S (which, i understand, is derived from some version of
BSD).  I think they've merged all the functionality in s/w and any use
of non-OTS h/w is more likely for energy efficiency and cost than

I understood (5+ years ago) that Cisco was moving in the direction of
providing Pix functionality on their routers ... but speculation is
pointless ... I'm sure all the info is on their site.
