We have succeeded to run SSH2 remote execution over HttpTunnel
by using JHttpTunnel(http://www.jcraft.com/jhttptunnel/) on MIDP emulator.
The source code is available at http://j2me.jsch.org/#jhttptunnel .
To enjoy this functionality, you need JHttpTunnel 0.0.3 and
then you have to apply the patch included in its archive to GNU httptunnel
