And equally you're over exaggerating the demands ZFS has; it runs quite happily on lower end hardware. Granted you need a 64bit CPU, but all Macs are shipped with one anyway. And unless you have deduping et al turned on (which you don't really want on a desktop anyway), the CPU load would be minimal. You could probably even get away without compression as well (though the modern algorithms ZFS supports are pretty light on the CPU).
As for memory, the minimum you need for pre-fetching is 2GB of free RAM. ZFS will, however, run on less with pre-fetching turned off.
The thing with ZFS is that it will consume your RAM and CPU if you have all the uber features enabled and a boat load of pools created, but since you don't need nor want that on a desktop, ZFS shouldn't need to be that resource hungry.
What's more, part of the misconception of ZFS's bloat comes from the age of the file system. My original ZFS server was less powerful than most budget laptops these days (and I was running a small number of VMs off that thing as well)! So modern systems definitely do have the resources to run ZFS as their desktop fs.
