userspace block driver?

Has anybody put any thought towards how a userspace block driver would work?

Consider a block device implemented via an SSL network connection. I
don't want to put SSL in the kernel, which means the only other
alternative is to pass data to/from a userspace daemon.

Anybody have any favorite methods? [similar to] mmap'd packet socket?
ramfs?

TIA,

Jeff
