A question about swapping

[James Mansion]

I'm looking for an operating system that I can use to build some 
diskless workstations.

I'd really like to be able to support swapping.

Is it feasible to enable swap to any remote file or remote block device 
with FreeBSD - without
risking a deadlock?

Linux seems to be prone to deadlock.  I don't know about Solaris.  I see 
that 7.0 will have an
iSCSI initiator - is there any work underway to support reliable swap 
against an iSCSI target?
