Emacs Multiple Session Manager + Android Termux Emacs GUI : Emacster: Master / Manager of many Emacs's .
Emacs can be asked to start a Server that listens on either a local UNIX domain socket (the default), OR on a TCP Socket .
On Android, there is Termux, and Emacs for Termux; in order to use it, you must switch to the Termux window and run the 'emacs' command in the terminal window. On Windows, there is Emacs for Windows, and MSYS2 / Cygwin bash shell, and Emacs can also listen on a TCP socket for Elisp code to run, and of course on ("UNIX" : (Linux / BSD / Solaris / AIX ...)) POSIX platforms, Emacs can be run natively without a bash shell or other environment being necessary. It would also be possible for an Android or Windows GUI application to Depend On Termux and Termux Emacs being installed (Android), or on Emacs for Windows being installed (Windows), or on just native Emacs being installed (Linux/UNIX), and to run it in Batch Mode on demand.
Emacster provides the ability to issue local or remote Termux/bash or Bash Shell or SSH commands to start up Emacs Servers in Batch Mode on demand, OR to issue commands to existing local or remote SSH connected devices running Emacs Servers over UNIX or TCP sockets, managing public key generation and exchange for remote hosts differently for different supported platforms with libssh2 and OpenSSL for (Linux / Android / Windows), to start up and Manage Emacs sessions, and to send Emacs Lisp (ELISP) expressions that create / destroy / modify (Edit) Emacs Buffers in those instances, and can Display lists of Buffers, Buffers, and WebKit HTML Renderings of HTML Buffers, if lib${X}WebKit is installed, to enable WYSIWYG HTML5 Editing , and which is able to start up / shutdown / query the status of those running instances , query their buffer lists, etc.
Emacster will detect when Multiple Users are editing the same buffer and will make the Shared Emacs Session use Locking and Guided Patch Merging to permit safe multiple user editing sessions.
If Dependencies: Emacs+Termux + picolisp (Android) or Emacs+MSYS2 + SBCL (Windows) or Emacs + SBCL (UNIX), or lib${X}WebKit or libssh2 or libxml2 or OpenSSL or bash shell or coreutils or tar / grep / sed / xz is not installed, Emacster will provide a FLTK GUI to guide their Installation.
On Linux, Emacster will be written mainly in ELISP + picolisp ,with a C/C++ Library, on Windows or other UNIX, picolisp will be replaced by SBCL Common LISP, and on all platforms Emacster will use FLTK for its GUI components, however on Android there will be an Android Java/Kotlin GUI Shell, and on Linux also it will use my SBCL Common LISP McCLIM FLTK port work ; all these will be based around a common C/C++ library, libEmacsSter.so, buildable on all platforms .
A future extension will be a full-featured 'EmacsterHTTPD' implementation that uses eww to display HTML5 and Mule Forms and provides CGI / HTML Submit Button processing support to provide a simple HTTPD / HTTPS/TCP/(((TLS+SSL) or VPN) socket) or HTTP/(UNIX-domain socket) server, and full integration with GIT and automatic SCM management of multi-user edited files, and a Chat Message facility with Teams or Google Chat / WebRTC integration for users who have buffers of the same file loaded.
