OK. I think you are in a case it is worth developping your own custom protocol between your client and your server. > - crc checking would be nice This is not required since TCP is a reliable transport protocol. > - large file support. (int64) No problem. Even without changing FReadCount (see Arno's message), except of course if you want to use this property that would warp aroung 2GB. Anyway changing it to Int64 is quick and easy. > - authentification. Easy. Better to implement a system where password never pass into clear text. Easy to send MD5 or SHA1 hash instead of the password.
