Which OS.

If you're running linux, read up on tmpfs (and/or unionfs).

Basically, you'll need to set all your lilypond stuff up in one 
directory. Then (if you're using tmpfs) copy that stuff into your tmpfs 
mount and run it from there.

If you use unionfs (which I don't actually know anything about) you may 
be able to declare that as ram and just mount it over your lily 
directory.

The difference between the two is that tmpfs simply creates a 
file-system in ram (masking the directory it's mounted over, hence you 
having to copy the lily stuff into that directory), while unionfs will 
create a "see through" filesystem over the mountpoint - any writes will 
go to the unionfs, while any reads, if they can't be found in the 
unionfs will look in the directory under the mount. So if you can mount 
the unionfs in ram, that's probably your best bet.

Cheers,
