If you need to distribute 240V around I'd suggest that you get a schuko power strip and put a US 240V plug on the other end. It was designed to handle 127-0-127 supplies.
Most 230V appliences will ship with Schuko plugs and they're easily availble as rewireables.
Also I'd be way happier working with VDE/Schuko fittings than with 240V US plugs. I don't like non-sheathed pin plugs and non recessed sockets.
Schuko's ideal for a non-polarised supply BS1363's fusing might complicate matters unnecessarily.
I was talking to an older electrician here recently and schuko sockets were in relatively widespread use in Ireland until the mid-1970s. As far as he was aware they are still an acceptable alternative to BS1363 but just not the norm.
He also had never heard the term schuko used to refer to them. They were know as "VDE sockets" and only VDE type 2 was ever allowed (i.e. with grounding clips)
