Let us discuss this situation. I have three employees in my company. I
put a closed derivative of a GPL'ed work on a company machine. I
refuse to give the employees the sources and tell them to use the
program for company business only.
Is this legal? As follows from the skipped part of your letter, there
are doubts. Let me now put it this way: if it is legal, then *I think*
it is legal to use non-quite-latex without renaming in these
circumstances. If it is not, then you cannot use it.

I was not clear enough. What I meant is this: if for any given
situation you have doubt what is legal under LPPL, try to substitute
"modification of LaTeX without renaming" by "use of closed derivative
of GPLed program without providing source and conferring the rights
guranteed by GPL". If the latter is legal in *this situation*, the
former is *probably* legal as well and vice versa.
If you don't drink it, someone else will.
