set your pproxy to buffer no more that 1 days worth of blocks - better to
underestimate than have too many blocks.
same with the client buffer counts - clients should also only buffer a days
worth of blocks max.
NOTE: there will be NEW PPROXIES released by monday that will be
required for use with any client newer than 2.7100

you need a client newer than build 396 -
set preferredcontest = 2
on clients newer than build 408
set processdes =1

clients newer then 408

contest switching on clients newer than build 396 is fully automatic
every time a client connects to a proxy it gets a message telling
it what contests are active - same with pproxys
>5. how much of this has been tested :)
well we got an unintentional test yesterday - a proxy got started with a bad
config file , and every client connecting to it did the switch :-)
we have a complete master-> proxy setup that we are using to test all the new builds
