PTP (IEEE 1588) needs custom interface hardware, though. The Ethernet
interface has added hardware to time stamp when the packet is sent/received,
and that's what the software uses to do the precision measurements.
I suppose one could (try to) use PTP over a wireless link. That would take an

Wireless for broadcast is generically a good idea (heck, I make my living doing
such stuff) but tricky.. Latency is a challenge if you want off-the-shelf
hardware.
The problem is that readily available wireless protocols (e.g. 802.11, 802.14,
802.16) are packet oriented, and more to the point,

Nice idea. Perhaps not so offbeat. Though bandwidth and radio don't
go too well toget

It's been an interesting thread, but I think I've come to the
conclusion that, except for a few financial market uses, such a device
is not really useful for bewoulf or HPC as the MISD model doesn't seem
to be of much practical use unless you can get something cute for
virtually free to suit occ
