Running with no swap isn't generally a good idea unless you've got a butt
load of ram, but if you have a butt load of ram you probably have a few gigs
to spare on your machine. *shrugs*
There is also a huge security concern if trying to dump the entire contents
of your ram to a remote location. All your passwords, encryption keys, web
sessions, and everything else will be transmitted and stored somewhere else.
Yikes.
I'm fairly sure this can be done if you prepare an appropriate
initrd/initramfs, but I seriously doubt any distribution supports anything
like this natively. You'd likely have to modify the initrd/initramfs by
hand.
Again, this is a very bad idea, but should be possible.
