Is it possible to boot current diskless?
Yes.
I'd say (from the times I tried it in 3.1 or something) to use netboot,
but that fails because it can't boot an ELF kernel.
net/etherboot port will do the job.
Should I build an aout kernel, and how do I do that for current?
etherboot knows FreeBSD elf.
Can I do it another way?
One might say that with the rc.diskless files in /etc, that it should
work somehow...
Sure it does. I use it. rc.diskless is powerfull and allow you to share
your server config (binaries + most configuration files) with bootp clients.
Here's the result for the currently running bootp client:

Note that 10.3.0.2 is breizh. DHCP port is running on breizh and serves
tftp/bootp requests to booting clients.
I use the following options in my client MACHINE files:
options BOOTP # Use BOOTP to obtain IP address/hostname
options BOOTP_NFSROOT # NFS mount root filesystem using BOOTP info
options BOOTP_COMPAT# Workaround for broken bootp daemons.
options BOOTP_WIRED_TO=ed1 # Use interface fxp0 for BOOTP
options MFS #Memory Filesystem
options NFS #Network Filesystem
pseudo-device vn 4 #Vnode driver (turns a file into a device)
