Hello guys!

I want to develop a web game based on Electrum.
Users can spent the number of bitcoins they want for having an "internal" coin usable in this game

I want to use electrum on the server in watch only mode, for generating 1 address per user.
Idealy each time a user does a deposit,  the system detects it and increase his "internal" coin wallet.

- If I understand well, if I run Electrum with the main secret phrase I will be able to also see all secondary addresses generated for users. It is only dependent to the gap limit. Am I right?

- Can we control created addresses in another way than gap limit? I'm expecting that several users will record on the website without deposit anything (because they would be not interested on the game, finally). So the risk would be to have more "fake" users than the gap limit allows it. I would appreciate something like "give me 1 new adress" method.

- I saw a script merchant.py which is not focused on my workflow but which could be a good base for it. Because it works a daemon, does it mean we do not need qt4 libs for this? (no GUI). In fact I don't know how qt would behave on a server without graphical interfaces.
A question around it is: can we use electrum purely in a shell?

- How can we help the electrum network? There is a network fee, but is there any "electrum network fee"?

Thanks,
Polux
