If integration is easy, and if we can show some improvement with webservers other than Flash, I'll help with integration. However, with the 5.2 code freeze starting in mid-November, I can't guarantee that we could have it integrated by then. However, that doesn't preclude us from doing work on it during that time. Does the version of flash available for download (.1 alpha) have the changes which take advantage of your enhanced sendfile integrated? Mike "Silby" Silbersack
