latedl uses the same functions to send the files, but also has reliable forward that fires on download completion. The focus is also somewhat different, latedl was ment to be used in such a way that all connected clients has the same files; while filenetmessages is more single-client oriented.

Yep, the last parameter for addlatedownload is a optional one that either takes client's index or zero for file broadcast.

Nope. There is a entirely different piece of code that handles fastdl during connection. These functions (CNetChan::SendFile) are only used as a fallback option when no fastdl is present.

My idea is if it is possible to download demo files from client or even screenshots, to implement some kind of anticheat plugin

I'm not sure whether upload from client still works in newer Valve titles, but even if it would, it would be pretty useless, for multiple of reasons. To download anything from client, you need to know it's full name; and the player would need to tell you that full name (i.e. via setinfo). The only exception is fixed name, like for custom sprays. Idea of downloading screenshots from clients is unreal, since you won't be able to trigger screenshot or demo capture in the first place.
