NOTE: With the economy as it is, the HBD is struggling to 
meet its meager operating expenses of approximately $3400
per year. If less than half of those currently directly
subscribed to the HBD sent in a mere $5.00, the HBD would
be able to easily meet its annual expenses, with room to 
spare for next year. Please consider it.

FYI - I was unable to find an answer to my question, so I ended up
contacting the manufacturer directly.
 
According to the manufacturer, the tubing I use is rated for use up to 
175F.  It is not recommended for use above this temperature due to
concerns relative to bursting.  There are no health concerns or FDA
food-grade issues when the tubing is used at near boiling temperatures
(212F).
 
I have used this type of tubing for around 10 years at near boiling
temperatures and low pressure (March pump).  During that time, I have
never had an issue with bursting.

For the last two years I've been using a Blichmann Beer Gun
in a straight bottle-filler (non-counterpressure) mode.  As
the level rises into the neck of the bottle you withdraw the
gun until the muzzle is just at the surface, give the
trigger a quick blip, and get a nice little packet of foam.

You can effect a crude approximation of the BBG by using a
replacement compression-fitting undersink rigid supply line
from the hardware store.  The flare at the end of the plated
brass tube is kinda sorta like the trumpet bell of the BBG.
It's what I used for several months after first reading
about the Beer Gun, until I had some cash freed up.   The
upper end of a keg dip tube is similar, but pricey.  You
still have to rig some sort of valve, or resort to the
kink-the-tube maneuver, but you're ahead by about $40.
