There was something called a "Clockport Expander" available, but I don't think they're made anymore. I saw one on Amibay or ebay last year. See link:

Also, there's schematics here for a home-brew project, a Clockport Splitter by "Rob the nerd":

So yes, it's possible to hook up a number of clockport devices at the same time. The Delfina sound card can be hooked up to any Amiga with a clockport, but it does need 68020 + fastram I believe. Yes, this card has an onboard DSP and can play mp3's without loading the CPU. There is some load on the CPU though due to having to transfer data through to the clockport.

These cards were available on amigakit until recently, there might be some cards left at additional amiga retailers.
