can u further explain it ??

write method of Stream (inherited by Serial) is declared virtual protected.

It would be nice if i could send a binary buffer in one one shot directly without making a putc() loop or deriving from Serial.

All the write method does is call putc in a while loop. Defining your own function to do that may be a tiny bit messier but isn't really that much of an issue and shouldn't cause any performance hit.
