It's 3rd time I'm asking for it ;-)
Even in new version of XPM client there is option to send some part of block found to address specified.
"* Added an automatic donation feature when a new block is found. The -donationpercentage allows a percentage of the block reward to be donated to an address. E.g. passing the command-line parameter -donationpercentage=1.5 will donate 1.5% of every block to the developer. Alternatively, this value can be set in primecoin.conf. Also, the default address can be changed using -donationaddress."
Anyway I dont think we will have solo miner fast, people are greeeeeeeedy ;-d and it seems there is hard co-operation of our beloved dev. and ypool for their 13%; dont forget that if miner is for only 1 pool that have bigger profit. I dont know for others are doing, but for me solo mining would mean more than double profit.
there is a solominer primegpu cost a 1 time fee of 35xpm per gpu dev had it at 65 but has since lowered it and refunded others back who knows it might get cheaper
on that note:
@claymore i hope some of the dev fees you are charging go to the creator of jhprimeminer since you are using a lot of his code
