In that setup, what is the relationship between the LC daemon and the
NgineX and Node daemons?

Linode has a good reputation, and I've also had good luck with VPSes
from InterServer and Chunkhost.

Interesting. I've used behaviors extensively for UI things, but hadn't
considered them for server use. What is the advantage there?

I can't say. I've never tried using LC Server as a daemon, and I don't
even use it as a CGI in production work, only for testing to help others.
I use Linux standalones run facelessly with -ui for all server apps,
mostly because it allows me to run and test everything in the IDE with
close to zero behavioral differences over runtime.
LC Server is a very good choice if you're accustomed to PHP-style
wokflows, but even when delivering Web pages I don't normally mix much
LC and HTML in the same file so calling the merge function explicitly is
as good for me as LC Server's implicit merge.
For non-HTML output, such as the binary data you're describing, either
the LC Server or desktop engines may do well with that (provided the
event and socket handling in Server is as good as it is in the desktop
engine), but using a standalone will allow the system to be MUCH more
