Chris, 1. Peter Zaitsev ran some tests which suggested that multiple .ibd files are not slower than one ibdata file. But it will depend on the OS version. Some OS'es may have bad fsync() implementation, which can cause slowdown with a large number of files.
2. Clustering? If you mean the fact that InnoDB stores the row data in the PRIMARY KEY index (= clustered index), that is also true for .ibd files. The only thing that changes is the file, not internal storage formats of tables.

Multiple table spaces eh? Funky! Of course, as you've no doubt become aware, I am one of these annoying people that has many questions to ask the list the moment something like this comes along! Please feel free to ignore these questions though, as we're all hanging out for 4.1.1. 1. Are there any performance implications (either way) with the use of multiple table spaces? Are there any other implications that you think are worthy of note (other than the obviously easier backup options). 2. Is there any way that clustering can still happen with multiple table spaces enabled?
