For those of you still looking at cluster stuff: I'd take a close look at www.scyld.com and see what they have. The key piece is bproc, which is now a sourceforge open source project set up by Erik Hendriks. You might want to look at bproc and see if that API could be implemented in FreeBSD. The

syscons dosn't automatically switch vtys if the keyboard is not in the XLATE mode. (Oh well, this isn't documented in vgl(3), *sigh*) In CODEKEYS and RAWKEYS modes, you need to initiate vty switching by yourself, by calling the ioctl VT_ACTIVATE when a key combination for vty switching is seen.
