Question

Answer 1

I'd suggest looking at Fossil - It's a single executable with no dependencies to run, operates all traffic over HTTP, keeps its all repository data in a single file which can be named anything, and includes version controlled wiki, bug tracking and a web-server out of the box. Oh, and it's completely distributed.
