Porsche 356 and E5 and E10 fuels

with the petrol companies being forced to add ethanol to fuel in what was E5, now E10, and in the future E20 and E30 what are other owners doing please to protect the fuel lines and carb internals against any fuel of the future.
is there an additive you can add in the certain times when only E5 or E10 are the only fuels available and not older fuels ?
many thanks

Running report of using alcohol containing fuels.
Just for information I have run our 1964 356C for the last 5000 miles using the 85E10 fuel in Europe and the 95 octane E5 fuel in UK without any problems so far. the engine is standard 8.5:1 compression ratio and the flexible fuel hoses are the modern type capable of handling alcohol based fuels. There have not been any leaks or starting or running problems using the cheap fuel. One thing about the later RHD cars is that the fuel tank is made from lead coated steel (Ternplate) so should not have any internal corrosion problems.
I also run my 1973 911S and the 1983 924 on the 5% ethanol 95 octane fuels and have done so ever since the fuels came into being. The MFI injection system seems to like, it but I had to renew all of the flexible fuel hoses after the old braid covered pipes started to leak while we were in France. 
All 3 cars have standard, unmodified engines with relatively low compression ratios.

I've switched to Esso high octane as it's ethanol free in most places. See:
