I know. But you didn't succeed. :) Two issues with using package names:

1. The names can then not change. At least not without problems.
2. The names can contain "tricky chars". Spaces, lower/upper case,
slashes etc. And guess what happens with those in filenames? :-) And
yeah, the package names would be limited to 31 chars.

It appears that there are already 12 packages with names longer than 21
(SMSqueakMap default packages collect: [:p | p name])
	select: [:n | n size > 31 ]

Hehe, now you are a bit harsh. Comparing SM with the M$ registry? ;-)

I know that readable names would have been nice - but I decided that I
want packages to be able to change names, and I also think the problems
with making package names work in all filesystems that Squeak supports
would be a hassle I don't have the energy to take on.

But hey, know what? You can *easily* whip up your *own* variant of
SMFileCache! Seriously! Take a look at that class. You only need to
implement ONE method:

SMFileCache>>directoryForPackageRelease: you can have any scheme you like! The only "problem" will be when
we start shipping preloaded caches.

Thanks. And as always - ideas on improvements or even offers of help
greatly appreciated. :)
