Following up on Valky's points for/against Filch being Tobias Snape in
hiding, 

Though I'm rather skeptical of the possibility, it occurred to me that
when Snape comes down to pick up Harry at the gate (HPB chapter 8),
Harry at first mistakes him for Filch.  This is actually the prelude
to the description of Snape that Marika quoted earlier on this thread,
in comparing Snape's and Pince's noses:

"A lantern was bobbing at the distant foot of the castle.  Harry was
so pleased to see it he felt he could even endure Filch's wheezy
criticisms of his tardiness and rants about how his timekeeping would
improve with regular application of thumbscrews.  It was not until the
glowing yellow light was ten feet away from them, and he had pulled
off his Invisibility Cloak so that he could be seen, that he
recognized, with a rush of pure loathing, the uplit hooked nose and
long, black, greasy hair of Severus Snape."

On first reading I wondered what made Harry think of Filch (last time
Harry had to be escorted in late it was Snape also, wasn't it?).
