I made my own DOS implementation (Announce)

I noticed mbbrutman's NetDrive and got some inspiration from it. I created NETDISK. Now ST-DOS has the power of cloud too.

Because ST-DOS has a different device driver API than MS-DOS and its 100% clones, NETDISK only works on ST-DOS. The way it works is pretty similar to mTCP NetDrive - the server computer has disk images and they are shared to the client computers. There are some differences though. Although NETDISK and mTCP NetDrive are products that serve different purposes and are not competing against each other, some comparisons between them can still be made:

NETDISK's pros, compared to mTCP NetDrive:
+ Works with all filesystem types (because ST-DOS has a filesystem driver API)
+ Has dynamic caching, which probably makes NETDISK faster
+ The server works on both DOS and POSIX-compatible operating systems like Linux (compiling it to DOS needs the socket.h header from ST-DOS's TCP/IP stack and its sockhdr.obj object file)
+ Works with almost indefinitely large drives (ST-DOS uses 64-bit offsets for device files)

Cons:
- Only works with ST-DOS
- No advanced features like sessions and "undo" - the server program is currently very simple and doesn't have a lot of code
- The device driver does not currently support unloading, a reboot is needed

I had to make some fixes to the kernel and the TCP/IP stack to get NETDISK working, so it only works with the newest versions of them.
