No complaints here.  Makes rational sense and adds some initial replay protection in the process.  People in the crypto community are seemingly quick on the draw to label everything an "attack" when it really isn't.  Just chalk it up to a difference of opinion and move on.  If there has to be a split, it should at least be done as cleanly as possible.  Everything about this decision is perfectly reasonable. 



As far as I know, it's just the code in the /btc1 repository for the moment.  The "2x" client is still in Alpha.  I'm led to understand that some new code is due for release tomorrow, but I don't know if that means a user-friendly installer or if it's more for the advanced tech-heads who are accustomed to compiling their own software.  There may be other wallet developers who said they might support it, but again, you'll probably have to wait a while before they release some compatible code.  Early days yet.
