This isnt a PW,
This is environment provisioning, for the purpose of hosting a module.
I've experimented with something similar in the past, where I hosted 'The_Hub'
which was a module that allowed users to add IP Addresses or host names which then went into a database, and then allowed people to travel to those PW's and use 'The Hub' as an airport of sorts.
I've since developed the system to the point where I am creating a website and people can create an account, apply for timeslots, and then upload their module, and resources, and have their module run during those times slots.
Now - the question remains: At the prices that Amazon charge for Linux Servers per hour, is this really viable, and is anyone really going to pay you for a service that they can get cheaper by doing it themselves?
Assuming someone's going to be paying for the provisioning of server environments? Right?
And also - you speak of seamless transitions - but the truth is that amazon servers spinning up takes about 5 minutes for linux, and longer for windows, unless your going for a higher spec server, which costs more.
Lower power = cheaper, but longer boot times.
All modules loaded will have access to the same ODBC, so persistent chests and quest varaibles could follow between modules.
You mention - 'All Modules Loaded':
Where are these coming from, are you basically providing a means for people to network their servers together, or are you suggesting you have created some online Modules that are ready to go.
From the description of the post, it looks like you've posted about an 'already conceived' concept, that is waiting for other people to adopt and use.
Rolo Kipp has been working on a Project called NWN Foundation with a few others, and I think part of that involves networking of servers (he can confirm if he sees this).
I'd just be warey of the way you word your original post.
You were advertising a PW, which is not what you have, you have an include file that you want people to pop in their modules, and then host their own servers.
And no doubt part of this would allow for travel from everyones server to everyones server using nwnx_vaultster or the like?
This would bypass peoples rulesets in their PW.
Conceptually, its a good idea, not unique or original, but a good idea, just need to work on some of the issues of cross server travel, thats why I used an 'airport' type module - to act as a 'customs' area, where server rulesets could be applied to the characters travelling.
