It is a free-tier asp.net website hosted on azure (no extra anything like VPS is required actually).
The setup is compiled with WIX, it looks like you can do that from a web-application without any issues (no admin rights are required).
1. Paul, sure you can put to your list

2. There is no signature at all, as far as I can tell. Why would I use my certificate to sign I don't know what ?

Not sure if signing can be done completely online.. Also it may not be that good idea - you'll need to specify a password for the certificate. Al tough this might be okay if security is properly implemented. The setup can be signed afterwards though.
3. There is no login/user credentials support for now (it's just not implemented - can be done of course in azure, but requires some effort). It's just a test run, of course there should be some security, at least edit/delete should be allowed only to the owner.
4. License and custom wizard images are also do-able of course, but are just not implemented yet. I just tried to keep everything as simple as possible.
If you think this makes sense, it could be added!
5. Language - German letters like "รถ" (or Cyrillic etc) may cause issues (also the generated setup now is always English) this language thing can be also addressed.
Need to add language support.
Chris, what do you mean by "file groups" - did not quite get that idea?
Anyways, I'm happy that you find it useful guys!
