I just found out why I'm having problems when merge mining TRC & WLC on the same p2pool node - it seems WLC is using the same ChainID return 0x0011 as TRC, which is obviously confusing my p2pool node:

Well, technically, since TRC just switched to merged mining...WLC had that chainID first...
It's a bit of conundrum as TRC is much more popular...
