I recently got bitten by this in the thread Portable in-memory files. In-memory files can be used as long as the functions you call just use open, close, <HANDLE>, print HANDLE etc.

They obviously can't be used when a module demands the (OS-internal) file descriptor. I presume Net::FTP is doing just that?
