Thanks much, I will take a look.  I have already found and read the code 
for NetBSD's iSCSI target.

I am mainly interested in 100% userspace solution, because in my case, 
the storage software (distributed goop) is also in userspace.  Something 
that exports through the kernel actually adds overhead, when a 
straight-to-sockets userspace implementation would be more efficient.
