I intended to get some people to test it quietly and then release it when stable, but everyone seems to be preoccupied. So here's a quite possibly very unstable alpha of Lacewing for Flash Player!
You can only connect to a server that is hosting a policy file that allows it. The server on aquadasoft.com port 6121 is open to connect to regardless of where you host your SWF, and the new version of the C++ library will enable hosting a policy file with the EXE server.
Put this in your Data\Runtime\Flash folder and you should be able to build a SWF that uses Lacewing. Let me know how it goes!
