For what I have heard, c2 at least doesn't have very large amount of subscribers (don't know about zulutrade, I'm really interested to hear if someone has a top system there) - I have talked one person who has one of the top ten forex systems at c2 (also quite cheap IMHO) and the subscriber count he mentioned wasn't really that good.
What I would do is to rent a cheap server, use mq4 publisher to publish my trades there and code a replicator for those trades. That way the subscriber validation is quite easy and real time - just require authentication with the server - and there is no way to decompile your EA.
I have had similar thoughts myself but so far I have decided to stick with just my trading, if you have a proper system then some kind of a percentage split (2-5% or something) of profits your clients make [only when the account goes higher] would be the best way to go assuming of course that you trust your results longer term.
