What solution would you recomend?

I used keyclone back in the day just to replicate keystrokes across EVE accounts, and I'm sure there are other free programs that would work for this. Targeting is your issue with having follower alts in EVE without having mouse replication. Try auto targeting missiles. Fit your main for tackle, regroup your alts to orbit you, fire away.

So perhaps if I could find something that would handle replication for the mouse too I could combine both to limited effectiveness? I will look at Keyclone to see if It will help me get part way like you suggested, thanks for that.

ISBoxer. I would use it if I only played 3 accounts.

ISBoxer seems like a quality piece of kit I won't deny but I have a real issue with subscription based software(s) and products. If they'd stick a $100 price tag or somesuch on ISBoxer and be done with it then I'd buy it in a heartbeat.
