A real runtime solution would require a D runtime interpreter or JIT 
compiler. There would be an alternative solution based on compiling each 
template to a shared library and then dynamically recompiling/reloading 
those as required, but that currently doesn't work due to the alias 
parameter based interface of render!(...).

However, what should work well is a combination of 
https://github.com/dlang/dub/pull/446 and 
https://github.com/rejectedsoftware/vibe.d/pull/1385 - I'll merge the 
latter one into vibe.d master today. It will require to store session 
information and similar things in an external store, and on Linux the 
Gold linker should be used for speed, but then it should be almost as 
good as a runtime solution.
