Is this project possible?

Awesome! Maximum respect to you.

Only in Linux. This, of course, can be worked around using IPC, but it's a bit of a hassle & takes more system resources.

Yes... as long as you're not doing too much allocation & never need to collect, you don't need a GC. Tango is a lot better than Phobos at this (look at Mango; it does very little allocation [= none] once the server has been set up.

Not the .NET Windows one, since the problem is only on Linux. Not sure about Mono.
