What about pushing BitcoinCash transaction?
Thank you
C.E. to da rescue:
http://blockdozer.com/insight/tx/sendThis doesn't have an API otherwise I would have added it to SharpPusher already...
Given that BitCoin XT is a direct clone of the Core wallet you can push a transaction yourself. (See my first post)
My code about the part "pushing the tx directly to the network" is nearly ready. I have not got the time to test it with real transaction yet. I can practically make a node with minimal functionality to just broadcast, I just have to make the code pretty and remove the bugs (DAMN BUSY LIFE).
Also I have no idea how to differentiate between nodes on different network. if you know how point me in the right direction and save me a google search

OTOH, BitCoinCash is a scale-able block concept, I'm guessing most punters will dial their "Pay only the minimum transaction fee" down to the bare minimum of 0.00001000 BCC/BCH per Kbyte as that BitCoin clone will probably sweep up all transactions and just grow the block size, so there won't be any real need to pay a little bit extra to get into the next block as the block will just keep growing to accommodate all transactions... QED.
Unless I'm mistaken?
According to
https://blockchair.com/bitcoin-cash/blocks the fee/kB (I don't know about the accuracy of it) is about 0.0009-0.0011 BCC/kB
