I've got a decent selection, if anyone wants to bug me about individual songs in IRC. I'm not giving out whole OSTS, though.
EDIT: "FFVII Piano Collections - I heard from a friend they exist. Anyone know of them?"
1 - Tifa's Theme
2 - Main Theme
3 - Cinco de Chocobo
4 - Ahead on our Way
5 - Fighting
6 - Cosmo Canyon
7 - Gold Saucer
8 - Farm Boy
9 - Rufus' Welcoming Ceremony
10 - J-E-N-O-V-A
11 - Aeris's Theme
12 - One Winged Angel
13 - Descendent of Shinobi
It's pretty good.
