@User: No, you cannot publish GDS generated from a non-free PDK. That is why you cannot find GDS files online anywhere, except those made using the SCMOS technologies from MOSIS, which are real processes that have been "obfuscated" by making all the design rules much more conservative (the goal is to make the rules scalable, but one side effect was to obfuscate them to the point that it was possible to make the SCMOS rules public).
