ah ok! i'll try at home this evening.
Btw i found this two sites in google cache:

This one and this one.

It looks like someone have already made an header, since the packages list contains:

enet.dll
enet.pas
enet_dyna.pas
enet_nocrc.dll

It should be great if i could save writing the headers, but codecentral looks not reachable for me ("Server too busy" they're on .NET framework.. How sad)

Anyone can reach it or have another link?
