I thought about doing something similar, but not exactly as you suggested. 
With the totcount package, you register the counters you'll want to keep track 
of with the 
It will create the counter thm@totc and set it to zero.  At the end of the run, 
the counter is 
written into first.tc.  I need to inform this file name to the next lecture.
So, inside the InPreamble, I registered all theorem counters.
Two problems resulted:
1. I got a lot of "!Missing number, treated as zero" errors.  
2. If I ignore the errors and finish the processing, the total counters of the 
environs that 
are NOT used in the document are written in first.tc, all set to zero, as 
The problem is that the counters that ARE used are again incremented every time 
the file 
is processed until all cross-references are right.
This time, I inserted the \setcounter{defn}{\totvalue{defn}}
command in the *.inc file.

That seems to work.  Thanks for pointing out the command.
So, I inserted 
\regtotcounter[auxfile=\currfilebase.tc]{thm}, etc
in the  appropriate places in the *.inc file.  The command \currfilebase comes 
from the 
currfile package.  It just contains the base file name, without the extension.
And then, if I know that in the next lecture the Definition and Exercise 
environs are used, 
inserting in the InPreamble

        \setcounter{xca}{\totvalue{xca}} }

does the trick.  The counters are set after all the rest of the preamble is 

Thank you.

Incidentally, in order to create locally the *.aux and *.tc files needed for 
I have to first export the document to LaTeX and then manually run 
pdflatex --draftmode <doc>

Is there a way to instruct Lyx to write certain auxiliary files into the local 
directory, instead 
of in /tmp/lyx_tmpdirxxx?
