"cipher none" alternatives ?

[Rob Hagopian]

There's an older thread about this, you can hack in none support really
easily, but I did performance tests between arcfour and none on Dual PIII
850Mhz machines and there was no significant performance difference. One
of the developers here asked for full profiling info but I haven't had
time to assemble it...
