It seems to me that there is no way to satisfy your demands except by

1. Modifying gdbserver - to support load and attach functionality
2. Modifying gdb remote protocol and remote.c to support remote process
   listing and remote attach.

IMHO, you can pretty much get by (1)developing minor modification of
gdbserver allowing it to optionally execute `continue' upon loading
the application and (2) writing a simple script which will ftp appcode and
start it under gdb server.

It is not going to be as cool but it will cover at least 90% of your
needs with a very minor development efforts.
