Yes, the only reason i used "insert-file" as the emacs command was
because this is the only elisp function that i could remember off the
top of my head which would have this effect :-) 

Briefly looking at the elisp docs i find that there is an  '(insert
"some text")' function which does exactly the correct thing, doh!. 

I've quickly looked at the code for emacsclient  and the protocol it
uses to communicate with  emacs (or at least the last process which
started its server) is very simple. Doing it this way might be more
consistent with the way that lyx works and also save having to worry
about which version of emacsclient you are using. 

For emacs 22 the default socket address is /tmp/emacs$UID/server (in
emacs 21 it is something else) and this is hard coded into emacsclient
(guess you might want to make this configurable though).

for a command like
emacsclient.emacs-snapshot --no-wait --eval '(insert "foo")' 

emacsclient opens the socket and writes the string to it:

-nowait -eval (insert&_\"foo\") \n

the string is quoted and the substitution appears to be: 
' '==>'&_'
'\n'==>'&n'
'&'==>'&&'
(based on emacs/lib-src/emacsclient.c) 

-nowait just tells emacs not to bother sending a response , which it
doesn't appear to do anyway, even when there is a failure (which i
assume is a bug).
