so can you tell me if i got this right: if i now use this version: https://github.com/jtoomim/p2pool/commits/1mb_segwit and mine on my own node, the following 3 conditions are fulfilled:

1) i join the network with 1.4 PHash visible here: http://p2pool.org/stats/
2) it is not possible to create orpahn blocks,as every node will signal segwit support
3) it will be possible to mine blocks in around three weeks, when there are normal tx as well as segwit tx in the bitcoin network. ( and get fees from both )
