Silly word games

[spudtater]

I've been trying to make the longest words possible with the shortest number of different letters. Without looking anything up on the internet (Edit: or writing perl scripts, clever though that may be), I've managed to think of:

N	Length	Letters	Word
2	5	e, s	esses
3	8	e, f, r	referrer
4	10	a, e, r, s	reassesses
5	13	e, g, i, n, r	reengineering

Can anybody think of any advances on those?

(Any reply involving the word 'smiles' will result in a swift, yet painful, death.)

sassafras 4 9
Woolloomooloo 4 13, if proper nouns count.

Arg! Cheating people!

(Though I accidentally deleted figg's Perl script as well as the generated word list... whoops)
