As Dieter pointed out, this can easily be shorted to just 
INSTANCE_HOME+'/Products', but that doesn't mean it'll be correct ;-)

Your best bet is DirectoryViews, but if you do ever want ot know the 
file system path of a Product, then put something like the following in 
the Product's __init__.py:

import os.path
my_path = os.path.abspath(os.path.split(__file__)[0])

...and then you can get it from elsewhere like:

from Products.MyProduct import my_path

cheers,

Chris
