So far I understand that from your point of view everyone has to learn Python to code a server for apps with lacewing extension and all Moo server should be redeveloped with Phyton. Both would mean costs.
In Forum I see that Lacewing seem to be in bug fixing state and not tested with client server based mass user apps.
Beside this I have not found pros for lacewing in comparison to Moo.
May I ask you to write some short statements.
