Why does an embedded system impose special considerations for
licensing? If you are concerned about distribution in binary only
form, this is allowed, provided that you give a reference to where the
source may be found. If you make the compression routine a seperate
task and tie it in with a pipeline, then you need not coply with the
GPL for the rest of your system, so what is the problem?

I think I commented that I did not remember the details here. Is it
that each user of Kermit must download his own copy, or what?
